Android 如何在自定义对话框按钮中使用intent？

我的对话框中有两个按钮，它们在xml文件中编码：

 <Button
    android:id="@+id/continuegame"
    style="?android:attr/buttonStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/resulttext"
    android:layout_marginRight="26dp"
    android:layout_marginTop="23dp"
    android:layout_toLeftOf="@+id/backmain"
    android:onClick="continueGame"
    android:text="@string/label_continue" />

<Button
    android:id="@+id/backmain"
    style="?android:attr/buttonStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBaseline="@+id/continuegame"
    android:layout_alignBottom="@+id/continuegame"
    android:layout_alignParentRight="true"
    android:layout_marginRight="52dp"
    android:onClick="backToMain"
    android:text="@string/label_mainmenu" />

试试这个

public void resultDialogBox(int correct){
    this.correct = correct;
    Dialog resultbox = new Dialog(GuessActivity.this);
    resultbox.setContentView(R.layout.dialog_result);
    resultbox.setCanceledOnTouchOutside(false);
    TextView result = (TextView) resultbox.findViewById(R.id.resulttext);
    Button continuegame = (Button) resultbox.findViewById(R.id.continuegame);
    Button backmain = (Button) resultbox.findViewById(R.id.backmain);

    if(correct == 1){
        result.setText("Correct!");
    } else {
        result.setText("Wrong!");
    }

    continuegame.setOnClickListener(new OnClickListener() {

          @Override
          public void onClick(View v) {
                  Intent con = new Intent(GuessActivity.this, PlayActivity.class);
                  GuessActivity.this.startActivity(con);
           }
    });

    backmain.setOnClickListener(new OnClickListener() {

          @Override
          public void onClick(View v) {
                  Intent backtomain = new Intent(GuessActivity.this, MainActivity.class);
                  GuessActivity.this.startActivity(backtomain);
           }
    });

    resultbox.show();

}

从XML中删除android:onClick=backToMain和android:onClick=continueGame。这是否意味着我应该将按钮方法放在我的dialogbox方法中？@user3266210是的，您不能使用它。因为该方法将把它作为活动单击。

public void resultDialogBox(int correct){
    this.correct = correct;
    Dialog resultbox = new Dialog(GuessActivity.this);
    resultbox.setContentView(R.layout.dialog_result);
    resultbox.setCanceledOnTouchOutside(false);
    TextView result = (TextView) resultbox.findViewById(R.id.resulttext);
    Button continuegame = (Button) resultbox.findViewById(R.id.continuegame);
    Button backmain = (Button) resultbox.findViewById(R.id.backmain);

    if(correct == 1){
        result.setText("Correct!");
    } else {
        result.setText("Wrong!");
    }

    continuegame.setOnClickListener(new OnClickListener() {

          @Override
          public void onClick(View v) {
                  Intent con = new Intent(GuessActivity.this, PlayActivity.class);
                  GuessActivity.this.startActivity(con);
           }
    });

    backmain.setOnClickListener(new OnClickListener() {

          @Override
          public void onClick(View v) {
                  Intent backtomain = new Intent(GuessActivity.this, MainActivity.class);
                  GuessActivity.this.startActivity(backtomain);
           }
    });

    resultbox.show();

}
