Question

我尝试使用不同的代码，但视频未在警告对话框中显示。我想在“警报”对话框中显示视频，但在我的情况下，仅显示警告对话框但未显示视频视图。

此处代码

<?php ... ?>

Popup.xml

AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this, R.style.AppTheme);
LayoutInflater inflater = getLayoutInflater();
View dialogView = inflater.inflate(R.layout.popup, null);
LinearLayout preview1 = (LinearLayout)dialogView.findViewById(R.id.preview);
VideoView videoView1 = new VideoView(getApplicationContext());
videoView1.setVideoURI(uri);
videoView1.setLayoutParams(layoutParams1);
videoView1.start();
preview1.addView(videoView1);
Alert alert = dialogBuilder.create();
Window window;
window = alert.getWindow();
window.setLayout(getMaxWidth(), 400);
window.setGravity(Gravity.CENTER);
WindowManager.LayoutParams lp = window.getAttributes();
lp.token = mInputView.getWindowToken();
lp.type = WindowManager.LayoutParams.TYPE_APPLICATION_ATTACHED_DIALOG;
window.setAttributes(lp);
lp.gravity = Gravity.TOP;
DisplayMetrics displaymetrics = new DisplayMetrics();
lp.x = 0;
lp.y = 600; 
window.addFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
alert.show();

请帮我解决这个问题。

Answer 1

试试这段代码

image.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) { 
// TODO Auto-generated method stub
// custom dialog
final Dialog dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.introvid);
dialog.show();
WindowManager.LayoutParams lp = new WindowManager.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
lp.copyFrom(dialog.getWindow().getAttributes());
dialog.getWindow().setAttributes(lp);
final VideoView videoview = (VideoView) dialog.findViewById(R.id.surface_view);
Uri uri=Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.introvideo);
videoview.setVideoURI(uri);
videoview.start();
}
});

尝试添加：

videoView.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 1));
            videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mp) {
                    videoView.setLayoutParams(new LinearLayout.LayoutParams(
                            ViewGroup.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
                }
            });

您的视频视图似乎没有拉伸到视频的大小。尝试将videoview的高度添加为1px，然后在加载视频后将其高度-设置为match_parent（宽度）和wrap_content（高度）
