從警報對話框按鈕打開鏈接Android

Question

我彈出一個警報框，要求用戶幫助翻譯兩個按鈕“幫助翻譯”和“關閉”，我該如何做，因此當用戶單擊“幫助翻譯”時，它將帶他們到網站example.com。

可以使用警告對話框來完成此操作，還是必須使用自定義框來制作布局文件

以及如何使“幫助翻譯”按鈕向左和“關閉”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

為PositiveButton和NegativeButton實現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);
       }
    });

您可以使用getButton（BUTTON_POSITIVE）;獲得按鈕。

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

然后，當您單擊“幫助翻譯”按鈕時，您可以執行以下操作：

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