android AlertDialog 捕获返回键

1、AlertDialog  捕获返回键的处理，使用setOnKeyListener事件可以。

2、AlertDialog  setView自定义的布局，去除上下左右的距离时使用的是：

builder.setView(shareView, 0, 0, 0, 0)，

并且还要用AlertDialog builder = new AlertDialog.Builder(ProductActivity.this).create();
;

 

AlertDialog builder = new AlertDialog.Builder(ProductActivity.this).create();
		builder.setTitle(R.string.share_here);
		View shareView = getLayoutInflater().inflate(R.layout.share_view, null);
		shareView.setPadding(0, 0, 0, 0);
		builder.setView(shareView, 0, 0, 0, 0);
		builder.setOnKeyListener(new OnKeyListener() {

			@Override
			public boolean onKey(DialogInterface dialog, int keyCode,
					KeyEvent event) {
				if (keyCode == KeyEvent.KEYCODE_BACK
						&& event.getRepeatCount() == 0) {
					isReturn = false;
				}
				return false;
			}
		});
		builder.setButton(getString(R.string.Ensure),
				new DialogInterface.OnClickListener() {

					@Override
					public void onClick(DialogInterface arg0, int arg1) {

					}
				});
		builder.show();
