从警报对话框按钮 Android 打开 Link

Question

我有一个弹出的警告框，要求用户帮助翻译两个按钮 "Help Translate" 和 "Close" 我如何做到这一点，所以当用户单击 "Help Translate" 时，它需要它们到网站 example.com。

这可以用警告对话框完成吗，还是我必须用自定义框制作布局文件

以及如何让 "Help Translate" 按钮向左，"Close" 向右

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    switch (item.getItemId()) {

    //noinspection SimplifiableIfStatement
    case R.id.action_about:
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setIcon(R.drawable.ic_launcher);
        builder.setTitle(getResources().getString(R.string.app_name));
        builder.setMessage(getResources().getString(R.string.about_text));
        builder.setNeutralButton("Close", null);
        builder.setCancelable(true);
        AlertDialog alert = builder.create();
        alert.show();
        return true;

        case R.id.action_translate:
            builder = new AlertDialog.Builder(this);
            builder.setIcon(R.drawable.ic_launcher);
            builder.setTitle(getResources().getString(R.string.app_name));
            builder.setMessage(getResources().getString(R.string.translate_text));
            builder.setPositiveButton ("Help Translate", null);
            builder.setNeutralButton("Close", null);
            builder.setCancelable(true);
            alert = builder.create();
            alert.show();
            return true;

Answer 1

为 PositiveButton 和 NegativeButton 实施 onClickListner()，例如

 builder.setNegativeButton("Close", new DialogInterface.OnClickListener()       {
      public void onClick(DialogInterface dialog, int whichButton) {
        // what ever you want to do with No option.
          builder.dismiss();
      }
    });

和

  builder.setPositiveButton("Help Translate", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
      builder.dismiss();
      Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.example.com"));
      startActivity(browserIntent);
       }
    });

Answer 2

您可以使用 getButton(BUTTON_POSITIVE);

获取按钮

http://developer.android.com/reference/android/app/AlertDialog.html#getButton(int)

然后您可以在单击“帮助翻译”按钮时执行类似的操作:

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);
