我可以创建和显示一个自定义警报对话框很好,但即使这样,我有android:layout_width/height=“fill_parent”在对话xml中,它只和内容一样大。
我想要的是填充整个屏幕的对话框,除了20像素的填充。 然后,作为对话框一部分的图像将自动使用fill_parent拉伸到完整的对话框大小。

当前回答
dialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT,WindowManager.LayoutParams.WRAP_CONTENT);

我的答案是基于koma的,但它不需要覆盖onStart,但只需要onCreateView,当你创建新的片段时,默认情况下几乎总是被覆盖。
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.your_fragment_layout, container);
Rect displayRectangle = new Rect();
Window window = getDialog().getWindow();
window.getDecorView().getWindowVisibleDisplayFrame(displayRectangle);
v.setMinimumWidth((int)(displayRectangle.width() * 0.9f));
v.setMinimumHeight((int)(displayRectangle.height() * 0.9f));
return v;
}
我在Android 5.0.1上进行了测试。
尝试将你的自定义对话框布局包装成RelativeLayout而不是LinearLayout。这对我很管用。
获取设备宽度:
public static int getWidth(Context context) {
DisplayMetrics displayMetrics = new DisplayMetrics();
WindowManager windowmanager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
windowmanager.getDefaultDisplay().getMetrics(displayMetrics);
return displayMetrics.widthPixels;
}
然后用它来制作对话90%的设备,
Dialog filterDialog = new Dialog(context, R.style.searchsdk_FilterDialog);
filterDialog.setContentView(R.layout.searchsdk_filter_popup);
initFilterDialog(filterDialog);
filterDialog.setCancelable(true);
filterDialog.getWindow().setLayout(((getWidth(context) / 100) * 90), LinearLayout.LayoutParams.MATCH_PARENT);
filterDialog.getWindow().setGravity(Gravity.END);
filterDialog.show();
final AlertDialog alertDialog;
LayoutInflater li = LayoutInflater.from(mActivity);
final View promptsView = li.inflate(R.layout.layout_dialog_select_time, null);
RecyclerView recyclerViewTime;
RippleButton buttonDone;
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(mActivity);
alertDialogBuilder.setView(promptsView);
// create alert dialog
alertDialog = alertDialogBuilder.create();
/**
* setting up window design
*/
alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
alertDialog.show();
DisplayMetrics metrics = new DisplayMetrics(); //get metrics of screen
mActivity.getWindowManager().getDefaultDisplay().getMetrics(metrics);
int height = (int) (metrics.heightPixels * 0.9); //set height to 90% of total
int width = (int) (metrics.widthPixels * 0.9); //set width to 90% of total
alertDialog.getWindow().setLayout(width, height); //set layout
recyclerViewTime = promptsView.findViewById(R.id.recyclerViewTime);
DialogSelectTimeAdapter dialogSelectTimeAdapter = new DialogSelectTimeAdapter(this);
RecyclerView.LayoutManager linearLayoutManager = new LinearLayoutManager(this);
recyclerViewTime.setLayoutManager(linearLayoutManager);
recyclerViewTime.setAdapter(dialogSelectTimeAdapter);
buttonDone = promptsView.findViewById(R.id.buttonDone);
buttonDone.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
alertDialog.dismiss();
}
});
***In Kotlin You can Code like This : -***
fun customDialog(activity: Activity?, layout: Int): Dialog {
val dialog = Dialog(activity!!)
try {
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
dialog.setCancelable(false)
dialog.setContentView(layout)
dialog.window!!.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
dialog.window!!.setLayout(ConstraintLayout.LayoutParams.MATCH_PARENT, ConstraintLayout.LayoutParams.WRAP_CONTENT);
dialog.show()
} catch (e: Exception) {
}
return dialog
}
