Set custom dialog height and width
提问by Vineet Kumar
I am making a custom dialog of which I want height and width to be default fit to all screen sizes.
我正在制作一个自定义对话框，我希望其高度和宽度默认适合所有屏幕尺寸。
But it is not happening so. The dialog is appearing very small though. THis is the XML for the dialog
但事实并非如此。虽然对话框看起来很小。这是对话框的 XML
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#D24379"
android:orientation="vertical" >
<TextView
android:id="@+id/txt_dia"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_margin="10dp"
android:textColor="@android:color/white"
android:textSize="15dp"
android:textStyle="bold" >
</TextView>
<LinearLayout
android:id="@+id/layButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:orientation="horizontal" >
<Button
android:id="@+id/yesButton"
android:layout_width="0.0dip"
android:layout_height="wrap_content"
android:layout_weight="1.0"
android:background="#ffffff"
android:text="@string/yes" />
<Button
android:id="@+id/noButton"
android:layout_marginLeft="5dp"
android:layout_width="0.0dip"
android:background="#ffffff"
android:layout_height="wrap_content"
android:layout_weight="1.0"
android:text="@string/no" />
</LinearLayout>
this is my dialog class
这是我的对话课
public class CustomDialogClass extends Dialog implements
android.view.View.OnClickListener {
public Activity c;
public Dialog d;
public Button yes, no;
public TextView content;
public CustomDialogClass(Activity a) {
super(a);
this.c = a;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.custom_dialog);
yes = (Button) findViewById(R.id.yesButton);
no = (Button) findViewById(R.id.noButton);
content=(TextView)findViewById(R.id.txt_dia);
yes.setOnClickListener(this);
no.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.yesButton:
break;
case R.id.noButton:
dismiss();
break;
default:
break;
}
dismiss();
}
}
How do I set the height and width to appear a default size such that it appears perfect on all screen size.

Not Dialog Class use, Try This Class :
不是对话框类使用，试试这个类：
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ShowDialog();
}
private void ShowDialog() {
// TODO Auto-generated method stub
final Dialog dialog = new Dialog(context,
android.R.style.Theme_Translucent_NoTitleBar);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.custom_dialog);
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(dialog.getWindow().getAttributes());
lp.width = WindowManager.LayoutParams.MATCH_PARENT;
lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
lp.gravity = Gravity.CENTER;
dialog.getWindow().setAttributes(lp);
Button yes = (Button) dialog.findViewById(R.id.yesButton);
yes.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog.dismiss();
}
});
Button no = (Button) dialog.findViewById(R.id.noButton);
no.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(
Intent.ACTION_PICK,
dialog.dismiss();
}
});
TextView content =(TextView) dialog.findViewById(R.id.txt_dia);
dialog.show();
}
}

In class extending Dialog :
在类扩展 Dialog ：
public MyPopUp(MainActivity activity, String sPrm) {
super(activity);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.alert_dialog);
LinearLayout bedLcl = (LinearLayout) findViewById(R.id.bed);
TextView textLcl = (TextView) findViewById(R.id.dialog_text);
textLcl.setText(sPrm);
setOnCancelListener(this);
DisplayMetrics displayMetrics = new DisplayMetrics();
activity.getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int widthLcl = (int) (displayMetrics.widthPixels*0.9f);
int heightLcl = (int) (displayMetrics.heightPixels*0.9f);
FrameLayout.LayoutParams paramsLcl = (FrameLayout.LayoutParams)
bedLcl.getLayoutParams();
paramsLcl.width = widthLcl;
paramsLcl.height =heightLcl ;
paramsLcl.gravity = Gravity.CENTER;
show();
Window window = getWindow();
bedLcl .setLayoutParams(paramsLcl);
window .setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));}
Correctly for all screens.
适用于所有屏幕。

Put this.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
in your custom dialog's onCreate()
放入this.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
您的自定义对话框onCreate()

You could add an android:gravity="center"to your LinearLayout and then set a minimum height on the LinearLayout as well, e.g. android:minHeight="120dp". You can then test your layout on various devices and tweak it until you get something that works on all screen sizes:
您可以android:gravity="center"向 LinearLayout添加，然后也可以在 LinearLayout 上设置最小高度，例如android:minHeight="120dp"。然后，您可以在各种设备上测试您的布局并对其进行调整，直到获得适用于所有屏幕尺寸的布局：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="120dp"
android:gravity="center"
android:background="#D24379"
android:orientation="vertical" >
