I am new to learning android, and I am writing a program to show a point and its position(coordination) on the screen.
I use TextView to show the coordinates, and using CustomView to draw the point out.
Here is my xml.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/mainRelativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="#+id/panel"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/tv_pointX"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_weight="1"
android:text="X : "
android:textSize="24sp" />
<TextView
android:id="#+id/tv_pointY"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_weight="1"
android:text="Y : "
android:textSize="24sp" />
</LinearLayout>
<com.example.pointnsendmsgtest3.svPaintCircle
android:id="#+id/TouchView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="0dp">
</com.example.pointnsendmsgtest3.svPaintCircle>
</LinearLayout>
</RelativeLayout>
And my main activity of the code. I am just wondering that how can I display all the views in one screen.
There is only one view can be displayed on the screen, base on the last setContentView command shows in my script to the compiler.
public class MainActivity extends Activity{
private TextView tv_pointx;
private TextView tv_pointy;
private LinearLayout panel_touch;
private svPaintCircle m_view;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
requestWindowFeature(Window.FEATURE_NO_TITLE);
m_view = new svPaintCircle(this);
m_view.setOnTouchListener(new MyListener());
setContentView(m_view);
setContentView(R.layout.activity_main);
}
public class MyListener implements View.OnTouchListener {
public boolean onTouch(View v, MotionEvent event){
testpoint(event);
return true;
}
private void testpoint(MotionEvent event){
if(!debugOn){
return;
}
//initialize mXs and mYs
ArrayList<Float> mXs = null;
ArrayList<Float> mYs = null;
if (mXs == null && mYs == null){
mXs = new ArrayList<Float>();
mYs = new ArrayList<Float>();
}
mXs.clear();
mYs.clear();
final int N = event.getPointerCount();
float x,y;
for(int i = 0; i < N; i++){
x = event.getX(event.getPointerId(i));
y = event.getY(event.getPointerId(i));
logd("x[" + i + "],y[" + i + "] = " + x + "," + y);
mXs.add(x);
mYs.add(y);
}
if(N > 0)m_view.setPoints(mXs,mYs);
}
}
private final boolean debugOn = true;
private final String TAG = "MyListener";
private int logd(String msg) {
int retVal = 0;
if (debugOn) {
retVal = Log.i(TAG, msg);
}
return retVal;
}
}
Here is the class how to draw the point immediately.
public class svPaintCircle extends android.support.v7.widget.AppCompatImageView {
public svPaintCircle(Context context){
super(context);
}
public svPaintCircle(Context context, AttributeSet attrs) {super(context, attrs);}
public svPaintCircle(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);}
#Override
protected void onDraw(Canvas canvas){
super.onDraw(canvas);
drawTouchPoint(canvas);
}
ArrayList<Float> mXs = null, mYs = null;
private boolean mDrawn = true;
private Paint mPointPaint = null;
private Paint mRectPaint = null;
private Paint mTextPaint = null;
public void setPoints(ArrayList<Float> mXs, ArrayList<Float> mYs){
if(debugOn) {
if(mPointPaint == null) {
mPointPaint = new Paint();
mPointPaint.setAntiAlias(false);
mPointPaint.setARGB(255,0,96,255);
mRectPaint = new Paint();
mRectPaint.setARGB(0x88,0x44,0x44,0x44); // 0x88 = 136 , 0x44 = 68
mTextPaint = new Paint();
mTextPaint.setTextSize(45);
mTextPaint.setARGB(0xff,0xff,0xff,0xff);
logd("init Paint");
}
this.mXs = mXs;
this.mYs = mYs;
mDrawn = false;
invalidate();
}
}
public void drawTouchPoint(Canvas canvas){
if(debugOn){
if(!mDrawn){
float x,y,rx,ry;
float dx = 80, dy = 80, r = 10;
for(int i = 0; i < mXs.size(); i++){
x = mXs.get(i);
y = mYs.get(i);
//draw cross
//canvas.drawLine(x, y - dy, x, y+dy, mPointPaint);
//canvas.drawLine(x - dx, y, x+dx ,y, mPointPaint);
canvas.drawCircle(x,y,r, mPointPaint);
rx = x;
ry = y - 40;
if(x + 75 > getRight())
rx = x -76;
if(ry < getTop())
ry = y + 20;
canvas.drawRect(0, 0, 320, 45, mRectPaint);
canvas.drawText("x: " + (int)x + " , y:" + (int)y, 0,35, mTextPaint);
}
mDrawn = true;
}
}
}
private final boolean debugOn = true;
private final String TAG = "PointView";
private int logd(String msg){

}
return retVal;
}
}
How can I make both TextView and CustomView shows together?
no, you can't. setContentView can only be done for one layout.
To add some value to my answer, I would assume your understanding of setContentView is a bit wrong. setContentView is how you tell android which layout file to associate with this activity (as per your example). that's how layouts with different components are done, it's one single file with multiple or different views inside one file (or being referenced from this file, with methods such as include in xml).
From the documentation:
Set the activity content from a layout resource. The resource will be inflated, adding all top-level views to the activity.

I am new to programming and I am trying to implement a flood fill algorithm to colorize selected part in the image as a color book app.
I have found this link which provides full working code (but slow) for the algorithm. and also provide QueueLinearFloodFiller which is way faster.
The problem is that The custom MyView class is added to Relativelayout to show the bitmap that will be colored but the image is out of the view like this
I want to wrap it to fill the view and take its size like in wrap_content
I have tried to use this code to resize it
dashBoard = (RelativeLayout) findViewById(R.id.dashBoard);
int width = RelativeLayout.LayoutParams.WRAP_CONTENT;
int hight = RelativeLayout.LayoutParams.WRAP_CONTENT;
myView.setLayoutParams(new RelativeLayout.LayoutParams(width,hight));
dashBoard.addView(myView);
but it didn't work.
here is the full code and the XML

Can Someone please help me to fix this
I have a setup in which I have some ImageViews around a center, and when the user clicks a Button, I want the Views to rotate around the center view, in an elliptical way.
What I have at current time is an elliptical movement, but the view is rotating in a weird axis, not on the center axis, as required.

</RelativeLayout>
tela_atomo_maca_central is the center element
tela_atomo_eletron_0 is the view I want to move elliptically
final ImageButton eletron = (ImageButton) findViewById(R.id.tela_atomo_eletron_0);
//Getting all points in the ellipse
for(int i=0;i<360;i++) {
double x = 46 * Math.cos(i);
double y = 78 * Math.sin(i);
Ponto p = new Ponto(x,y);
pontos.add(p);
}
Runnable eletronRunnable = new Runnable() {
#Override
public void run() {
if (contagem < 360) {
Ponto p = pontos.get(contagem);
contagem++;
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) eletron.getLayoutParams();
params.rightMargin = (int)p.getX();
params.bottomMargin = (int)p.getY();
eletron.setLayoutParams(params);
eletron.postDelayed(this,100);
}else {
contagem = 0;
eletron.postDelayed(this,100);
}
}
};
eletron.postDelayed(eletronRunnable,100);
}
private class Ponto {
private double x,y;
public Ponto(double x, double y) {
this.x = x;
this.y = y;
}
public double getX() {
return x;
}
public double getY() {
return y;
}
}
I'm probably making logical mistakes, because I can make it move elliptically, just not where I want.
How can I make the Image move elliptically around the center?
Based on your existing code I made a sample project and here is what I acheived -
Here is the modified code -
public class ActivityTest extends AppCompatActivity {
ImageButton eletron,center;
ArrayList<Ponto> pontos = new ArrayList<>();
int contagem = 0;
DemoRelativeLayout rel;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.so_demo);
eletron = (ImageButton) findViewById(R.id.tela_atomo_eletron_0);
center = (ImageButton) findViewById(R.id.tela_atomo_maca_central);
rel = (DemoRelativeLayout)findViewById(R.id.demo);
//Getting all points in the ellipse
for(int i=0;i<360;i++) {
double x = (200 * Math.cos(i));
double y = (400 * Math.sin(i));
Ponto p = new Ponto(x,y);
pontos.add(p);
}
eletron.postDelayed(eletronRunnable,2000);
}
#Override
protected void onStart() {
super.onStart();
rel.drawCircle(pontos,center.getX() + center.getWidth()/2,center.getY() + center.getHeight()/2);
rel.invalidate();
}
Runnable eletronRunnable = new Runnable() {
#Override
public void run() {
if (contagem < 360) {
Ponto p = pontos.get(contagem);
contagem++;
/*RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) eletron.getLayoutParams();
params.rightMargin = (int)p.getX();
params.bottomMargin = (int)p.getY();
eletron.setLayoutParams(params);*/
eletron.setTranslationX((float) p.getX() + (eletron.getWidth()/2 + center.getWidth()/2));
eletron.setTranslationY((float)p.getY() + (eletron.getHeight()/2 + center.getHeight()/2));
eletron.postDelayed(this,100);
}else {
contagem = 0;
eletron.postDelayed(this,100);
}
}
};
public class Ponto {
private double x,y;
public Ponto(double x, double y) {
this.x = x;
this.y = y;
}
public double getX() {
return x;
}
public double getY() {
return y;
}
}
}
I have also changed the xml file -
<com.wandertails.stackovrflw.DemoRelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

<ImageButton
android:layout_width="40dp"
android:layout_height="40dp"
android:id="#+id/tela_atomo_maca_central"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:src="#444444"
android:background="#null"/>
<ImageButton
android:layout_width="40dp"
android:layout_height="40dp"
android:id="#+id/tela_atomo_eletron_0"
android:src="#880080"
android:background="#null"
android:layout_toLeftOf="#+id/tela_atomo_maca_central"
android:layout_above="#+id/tela_atomo_maca_central"/>
</com.wandertails.stackovrflw.DemoRelativeLayout>
Finally the DemoRelativeLayout if you want to draw the elliptical path -
public class DemoRelativeLayout extends RelativeLayout
{
ArrayList<ActivityTest.Ponto> pontos;
float cntrX,cntrY;
public DemoRelativeLayout(Context context) {
super(context);
}
public DemoRelativeLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public DemoRelativeLayout(Context context, AttributeSet attrs, intdefStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Override
protected void dispatchDraw(Canvas canvas) {
super.dispatchDraw(canvas);
if(pontos != null){
Paint p = new Paint();
p.setColor(Color.RED);
for (ActivityTest.Ponto pt : pontos){
float x = (float)pt.getX() + cntrX;
float y = (float)pt.getY() + cntrY;
canvas.drawCircle(x,y,5,p);
}
}
}
public void drawCircle(ArrayList<ActivityTest.Ponto> pp,float x,float y){
cntrX = x;
cntrY = y;
pontos = pp;
}
}
I hope this is all you want..

I really need help here. I have project which call MyHeartRate, I downloaded the source code of heart rate project at Github. So I try to run that source code and there is no error. In the interface layout, it display the "camera". Example, when you open your camera then you will see the screen focus on what area that you want to take the picture. So my problem is, I want to remove that "camera" in my layout. I need to know which code need to be delete so then the "camera" not in my layout.
here's my code

tq,

I found the answer. just comment this code
//preview = (SurfaceView) findViewById(R.id.preview);
//previewHolder = preview.getHolder();
//previewHolder.addCallback(surfaceCallback);
//previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
done.
