I wanna set maximum height of dialog. Not custom height like that set by dp or px. I wanna set the greatest possible height to dialog relatively current device screen size.
You can not set max height directly. Just an alternate, you can reset height if its height is greater than maximum height you want to set.
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(dialog.getWindow().getAttributes());
int dialogWidth = lp.width;
int dialogHeight = lp.height;
if(dialogHeight > MAX_HEIGHT) {
d.getWindow().setLayout(dialogWidth,MAX_HEIGHT);
}
Dialog dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.dialog_example);
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(dialog.getWindow().getAttributes());
lp.width = WindowManager.LayoutParams.WRAP_CONTENT;
lp.height = WindowManager.LayoutParams.MATCH_PARENT;
//lp.height = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 330/*height value*/, getResources().getDisplayMetrics()); for custom height value
dialog.getWindow().setAttributes(lp);
dialog.show();
I think this can solve it. I've added two way one is for set dialog height with match parent property and second one is for setting height with custom value
may be addOnLayoutChangeListener() is usefull for you.
you can add it before or after dialog.show()
this is my code :
AlertDialog.Builder builder = new AlertDialog.Builder(this);
final View view = LayoutInflater.from(this).inflate(R.layout.custom_alertdialog, null);
builder.setMessage("TestMessage xxxxxxx");
builder.setPositiveButton("ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
builder.setView(view); //在setView之前调用builder的原有设置控件方法时，能展示设置的控件，之后设置的则不展示！！
AlertDialog dialog = builder.create();
dialog.getWindow().setBackgroundDrawable(getResources().getDrawable(R.drawable.shape_bk_cnoneralert));
//builder.show(); //用这个的话，背景并不会改变,依旧是默认的
dialog.show(); //必须用这个show 才能显示自定义的dialog window 的背景
//这种设置宽高的方式也是好使的！！！-- show 前调用，show 后调用都可以！！！
view.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
#Override
public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop,
int oldRight, int oldBottom) {
int height = v.getHeight();
int contentHeight = view.getHeight();
LogUtils.e("高度", height + " / " + " / " + contentHeight);
int needHeight = 500;
if (contentHeight > needHeight) {
//注意：这里的 LayoutParams 必须是 FrameLayout的！！
//NOTICE : must be FrameLayout.LayoutParams
view.setLayoutParams(new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,
needHeight));
}
}
});
DisplayMetrics displaymetrics = new DisplayMetrics();
getActivity().getWindowManager().getDefaultDisplay()
.getMetrics(displaymetrics);
int width = (int) (displaymetrics.widthPixels);
int height = (int) (displaymetrics.heightPixels);
d.getWindow().setLayout(width,height);
d.show();
Where d is dialog. This code sets the dialog to full screen.

I am creating a custom ViewGroup. I does need to have 2 FrameLayout one above the other; the one that stays to the bottom must be 20dp, while the other one must cover the rest of the view.
onMeasure
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int widthMode = MeasureSpec.getMode(widthMeasureSpec);
int heightMode = MeasureSpec.getMode(heightMeasureSpec);
int widthSize = MeasureSpec.getSize(widthMeasureSpec);
int heightSize = MeasureSpec.getSize(heightMeasureSpec);
setMeasuredDimension(widthSize, heightSize);
final View content = getChildAt(CONTENT_INDEX);
final View bar = getChildAt(BAR_INDEX);
content.measure(
MeasureSpec.makeMeasureSpec(widthSize, MeasureSpec.EXACTLY),
MeasureSpec.makeMeasureSpec(heightSize - getPixels(BAR_HEIGHT), MeasureSpec.EXACTLY)
);
bar.measure(
MeasureSpec.makeMeasureSpec(widthSize, MeasureSpec.EXACTLY),
MeasureSpec.makeMeasureSpec(getPixels(BAR_HEIGHT), MeasureSpec.EXACTLY)
);
onLayout
#Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
mInLayout = true;
final View content = getChildAt(CONTENT_INDEX);
final View bar = getChildAt(BAR_INDEX);
if (content.getVisibility() != GONE) {
content.layout(0, 0, content.getMeasuredWidth(), content.getMeasuredHeight());
}
if (bar.getVisibility() != GONE) {
bar.layout(0, content.getMeasuredHeight(), bar.getMeasuredWidth(), 0);
}
mInLayout = false;
mFirstLayout = false;
}
}
The views I am adding to this custom ViewGroup
LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
mContentContainer = new FrameLayout(getContext());
mContentContainer.setLayoutParams(lp);
mBarContainer = new FrameLayout(getContext());
mBarContainer.setLayoutParams(lp);
// ... adding stuff to both containers ....
addView(mContentContainer, 0);
addView(mBarContainer, 1);
The issue
mContentContainer gets rendered correctly (from top=0 to bottom=(totalHeight - bar height) and match parent for the width), while the bar is not rendered.
The last parameter in the View#layout() method is the bottom of the View. For your bar, you're passing 0, but it should be the height of your custom View, which you can figure from the t and b values passed into onLayout().
bar.layout(0, content.getMeasuredHeight(), bar.getMeasuredWidth(), b - t);
I want to use QuickAction dialog in my learning App, but I don't know how to change the size of the dialog. Now, the dialog is close to phone border, but I want to left blank between borders or reduce the width.
Thanks~
call setRootViewId(R.layout.notify_quick_action); at constructor.
public void setRootViewId(int id) {
mRootView = (ViewGroup) inflater.inflate(id, null);
mTrack = (ViewGroup) mRootView.findViewById(R.id.tracks);
mArrowDown = (ImageView) mRootView.findViewById(R.id.arrow_down);
mArrowUp = (ImageView) mRootView.findViewById(R.id.arrow_up);
mRootView.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
setContentView(mRootView);
}
call show() at setOnItemClickListener()
public void show (View anchor) {
preShow();
int[] location = new int[2];
mDidAction = false;
anchor.getLocationOnScreen(location);
Rect anchorRect = new Rect(location[0], location[1], location[0] + anchor.getWidth(), location[1]
+ anchor.getHeight());
mRootView.measure(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
int rootWidth = mRootView.getMeasuredWidth();
int rootHeight = mRootView.getMeasuredHeight();
int screenWidth = mWindowManager.getDefaultDisplay().getWidth();
int xPos = (screenWidth - rootWidth) / 2;
int yPos = anchorRect.top - rootHeight;
boolean onTop = true;
if (rootHeight > anchor.getTop()) {
yPos = anchorRect.bottom;
onTop = false;
}
showArrow(((onTop) ? R.id.arrow_down : R.id.arrow_up), anchorRect.centerX()+180);
setAnimationStyle(screenWidth, anchorRect.centerX(), onTop);
Log.d("-------", "xPos="+xPos+";yPos="+yPos+";rootWidth="+rootWidth+";rootHeight="+rootHeight+";screenWidth="+screenWidth);
mWindow.showAtLocation(anchor, Gravity.NO_GRAVITY, 100, yPos);
if (mAnimateTrack) mTrack.startAnimation(mTrackAnim);
}
Just use custom PopupWindow. Yeah, here link:
https://androidresearch.wordpress.com/2012/05/06/how-to-create-popups-in-android/
using a dialog as a window I tried to set its layout as
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.x = 120;
lp.y = 120;
lp.width = 800;
lp.height = 450;
Dialog dialog = new Dialog(cxt);
dialog.getWindow().setAttributes(lp);
dialog.setContentView(vFirst);
dialog.show();
where
View vFirst = inflater.inflate(R.layout.popup, container, false);
which is inside a button click,but it is not setting it.
I think you should use this
dialog.getWindow().setLayout(800, 450);
This will set the dialog window size.
public class Myclass extends Dialog
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LayoutParams params = getWindow().getAttributes();
params.height = LayoutParams.FILL_PARENT;
getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
}
}
layout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:id="#+id/dialogWidth"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
// contents here
</LinearLayout>
According to documentation: http://developer.android.com/reference/android/view/WindowManager.LayoutParams.html,
X position for this window. With the default gravity it is ignored. When using LEFT or START or RIGHT or END it provides an offset from the given edge.
Y position for this window. With the default gravity it is ignored. When using TOP or BOTTOM it provides an offset from the given edge.
So to make x and y work you should set Gravity attribute before. For example:
lp.gravity = Gravity.TOP;
lp.gravity = Gravity.LEFT;
lp.y = 120;
lp.x = 120;
//dialog width and height are set according to screen, you can take you want
Dialog myDialog = new Dialog(context, R.style.CustomTheme);
myDialog.setContentView(R.layout.share_post_dialog);
int[] widthHeight = getDeviceWidthAndHeight(context);
int dialogHeight = widthHeight[1] - widthHeight[1] / 4;
int dialogWidth = widthHeight[0] - widthHeight[0] / 5;
WindowManager.LayoutParams params = myDialog.getWindow().getAttributes();
params.width= dialogWidth;
params.height = dialogHeight;
myDialog.getWindow().setAttributes((WindowManager.LayoutParams) params);
myDialog.show();
//This is used to get height width of screen
#SuppressWarnings("deprecation")
public static int[] getDeviceWidthAndHeight(Context context) {
int widthHeght[] = new int[2];
int measuredWidth = 0;
int measuredHeight = 0;
WindowManager w = (WindowManager) context
.getSystemService(Context.WINDOW_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
Point size = new Point();
w.getDefaultDisplay().getSize(size);
measuredWidth = size.x;
measuredHeight = size.y;
widthHeght[0] = measuredWidth;
widthHeght[1] = measuredHeight;
} else {
Display d = w.getDefaultDisplay();
measuredWidth = d.getWidth();
measuredHeight = d.getHeight();
widthHeght[0] = measuredWidth;
widthHeght[1] = measuredHeight;
}
return widthHeght;
}
I want to manage the height and width of an EditText box programmatically in Android. I tried edittext.setWidth(32); and edittext.setEms(50);, but both are not working. See my below code, as I am using it to create dynamic EditTexts in Android.
private EditText createEditText()
{
final LayoutParams lparams = new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT);
final EditText edittext = new EditText(this);
edittext.setLayoutParams(lparams);
edittext.setWidth(32);
edittext.setEms(50);
return edittext;
}
private EditText createEditText()
{
final LayoutParams lparams = new LayoutParams(50,30); // Width , height
final EditText edittext = new EditText(this);
edittext.setLayoutParams(lparams);
return edittext;
}
Try this.
edittext.getLayoutParams().width=32;
DisplayMetrics metrics = new DisplayMetrics();
WindowManager wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
wm.getDefaultDisplay().getMetrics(metrics);
final float height = metrics.heightPixels;
EditText edittext = new EditText(this);
edittext.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,(int) (height/2)));
RelativeLayout.LayoutParams.width = 32;
RelativeLayout.LayoutParams.height = 50;
works for me. for example
lparams.width = 32;
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) edittext.getLayoutParams();
params.width = mScreenWidth / 5;
params.height = mScreenWidth / 5;
edittext.setLayoutParams(params);
Try the following code:-
Display display = getWindowManager().getDefaultDisplay();
int screenWidth = display.getWidth();
int screenHeight = display.getHeight();
profile_pic.getLayoutParams().height=(screenHeight/6);
profile_pic.getLayoutParams().width=(screenHeight/6);
I have a problem in setting the height and width of an Alert Dialog, below is my Code that i have written in OnCreateDialog() method:
AlertDialog dialog = new AlertDialog.Builder(context ,AlertDialog.THEME_HOLO_LIGHT)
.setTitle("Title")
.setAdapter(adapter, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
switch(which){
case 0:
//some Code
break;
case 1:
//some Code
break;
}
}
})
.create();
WindowManager.LayoutParams WMLP = dialog.getWindow().getAttributes();
WMLP.x = 80; //x position
WMLP.y = -100; //y position
WMLP.height = 100;
WMLP.width = 100;
dialog.getWindow().setAttributes(WMLP);
//OR
dialog.getWindow().setLayout(100, 100);
Kindly tell me what is the problem here in the Code. Thanks
You need to set the parameters for Height & Width after alertDialog.show();
So you need to call,
alertDialog.getWindow().setLayout(100, 100);
After calling
alertDialog.show();
