java - 从警报对话框按钮打开链接 Android

Question

我有一个弹出的警告框，要求用户帮助翻译两个按钮“帮助翻译”和“关闭”我如何做到这一点，当用户点击“帮助翻译”时，它会将他们带到网站 example.com .

这可以用警告对话框来完成还是我必须用自定义框制作一个布局文件

还有如何让“帮助翻译”按钮向左，“关闭”按钮向右

@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 实现onClickListner()

 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);
       }
    });
