dialogandroid定位,在屏幕android上更改Dialog的位置

在屏幕android上更改Dialog的位置

我在我的活动中做了一个简单的AlertDialog&＃xff1a;

View view &＃61; layoutInflater.inflate(R.layout.my_dialog, null);

AlertDialog infoDialog &＃61; new AlertDialog.Builder(MyActivity.this)

.setView(view)

.create();

infoDialog.show();

使用上面的代码&＃xff0c;对话框显示在屏幕的中心(大约)。

我想知道&＃xff0c;如何自定义对话框位置以使其显示在顶部操作栏下&＃xff1f; (无论如何改变对话的重力或某些东西&＃xff1f;)以及如何根据我的代码做到这一点&＃xff1f;

我使用此代码显示屏幕底部的对话框&＃xff1a;

Dialog dlg &＃61; ;

Window window &＃61; dlg.getWindow();

WindowManager.LayoutParams wlp &＃61; window.getAttributes();

wlp.gravity &＃61; Gravity.BOTTOM;

wlp.flags &&＃61; ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;

window.setAttributes(wlp);

如果需要&＃xff0c;此代码还可以防止android调暗对话框的背景。 您应该能够更改重力参数以移动对话框

private void showPictureialog() {

final Dialog dialog &＃61; new Dialog(this,

android.R.style.Theme_Translucent_NoTitleBar);

// Setting dialogview

Window window &＃61; dialog.getWindow();

window.setGravity(Gravity.CENTER);

window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);

dialog.setTitle(null);

dialog.setContentView(R.layout.selectpic_dialog);

dialog.setCancelable(true);

dialog.show();

}

您可以根据重力和布局参数自定义对话框根据您的要求更改重力和布局参数

对我来说&＃xff0c;这很好用&＃xff0c;我试图将对话框放在textview底部的某个位置&＃xff0c;在那里它被选中。

public void setPosition(int yValue) {

Window window &＃61; getWindow();

WindowManager.LayoutParams param &＃61; window.getAttributes();

param.gravity &＃61; Gravity.TOP | Gravity.CENTER_HORIZONTAL;

param.y &＃61; yValue;

window.setAttributes(param);

window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

}

我在这里找到了&＃64;gypsicoder代码的代码片段

private CharSequence[] items &＃61; {"Set as Ringtone", "Set as Alarm"};

AlertDialog.Builder builder &＃61; new AlertDialog.Builder(this);

builder.setItems(items, new DialogInterface.OnClickListener() {

public void onClick(DialogInterface dialog, int item) {

if(item &＃61;&＃61; 0) {

} else if(item &＃61;&＃61; 1) {

} else if(item &＃61;&＃61; 2) {

}

}

});

AlertDialog dialog &＃61; builder.create();

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

WindowManager.LayoutParams wmlp &＃61; dialog.getWindow().getAttributes();

wmlp.gravity &＃61; Gravity.TOP | Gravity.LEFT;

wmlp.x &＃61; 100; //x position

wmlp.y &＃61; 100; //y position

dialog.show();

这里x位置的值是从左到右的像素。 对于y位置值是从下到上。

新BottomSheetDialog&＃xff1a;

BottomSheetDialog dialog &＃61; new BottomSheetDialog(YourActivity.this);

dialog.setContentView(YourView);

dialog.show();

只需将其添加到您的代码中&＃xff1a;

dialog.getWindow().setGravity(Gravity.BOTTOM);

public class MyDialogFragment extends DialogFragment{

protected void setDialogGravity(int gravity) {

Dialog dialog &＃61; getDialog();

if (dialog !&＃61; null) {

Window window &＃61; dialog.getWindow();

if (window !&＃61; null) {

WindowManager.LayoutParams params &＃61; window.getAttributes();

params.width &＃61; WindowManager.LayoutParams.MATCH_PARENT;

params.height &＃61; WindowManager.LayoutParams.MATCH_PARENT;

params.horizontalMargin &＃61; 0;

params.gravity &＃61; gravity;

params.dimAmount &＃61; 0;

params.flags &&＃61; ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;

window.setAttributes(params);

}

}

}

&＃64;Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

super.onCreateView(inflater,container,savedInstanceState);

return inflater.inflate(R.layout.my_dialog, null);

}

&＃64;Override

public void onViewCreated(View view, &＃64;Nullable Bundle savedInstanceState) {

super.onViewCreated(view, savedInstanceState);

setDialogGravity(Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL);

}

}
