在屏幕android上更改Dialog的位置

Question

我AlertDialog在我的活动中做了一个简单的事:

View view = layoutInflater.inflate(R.layout.my_dialog, null);
AlertDialog infoDialog = new AlertDialog.Builder(MyActivity.this)
                    .setView(view)  
                    .create();

infoDialog.show();

使用上面的代码,对话框显示在屏幕的中心(大约).

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

Answer 1

我使用此代码显示屏幕底部的对话框:

Dialog dlg = <code to create custom dialog>;

Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();

wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);

如果需要,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

Answer 2

private void showPictureialog() {
    final Dialog dialog = new Dialog(this,
            android.R.style.Theme_Translucent_NoTitleBar);

    // Setting dialogview
    Window window = 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

Answer 3

对我来说,这很好用,我试图将对话框放在textview底部的某个位置,在那里它被选中.

public void setPosition(int yValue) {
    Window window = getWindow();
    WindowManager.LayoutParams param = window.getAttributes();
    param.gravity = Gravity.TOP | Gravity.CENTER_HORIZONTAL;
    param.y = yValue;
    window.setAttributes(param);
    window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
}

Answer 4

我在这里找到了@gypsicoder代码的代码片段

private CharSequence[] items = {"Set as Ringtone", "Set as Alarm"};
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setItems(items, new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int item) {

        if(item == 0) {

        } else if(item == 1) {

        } else if(item == 2) {

        }
    }
});

AlertDialog dialog = builder.create();
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
WindowManager.LayoutParams wmlp = dialog.getWindow().getAttributes();

wmlp.gravity = Gravity.TOP | Gravity.LEFT;
wmlp.x = 100;   //x position
wmlp.y = 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:

BottomSheetDialog dialog = new BottomSheetDialog(YourActivity.this);    
dialog.setContentView(YourView);

dialog.show();

Answer 6

只需将其添加到您的代码中：

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