Android 自定义对话框

自定义对话框样式：activity_direction.xml

Activity样式：activity_main.xml

Activity代码：

mButtonSetDirection.setOnClickListener(new OnClickListener(){


@Override
public void onClick(View view) {
showDirectionDialog();
}
});

protected void  showDirectionDialog() {
final Dialog dialog = new Dialog(MainActivity.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.activity_direction);
 
final Button button_submit = (Button)dialog.findViewById(R.id.button_submit);
final Button button_reset = (Button)dialog.findViewById(R.id.button_reset);

button_submit.setOnClickListener(new OnClickListener(){


@Override
public void onClick(View view) {
clearSpinner();
myView.onRedraw();
dialog.dismiss();
}
});

button_reset.setOnClickListener(new OnClickListener(){


@Override
public void onClick(View view) {
dialog.dismiss();
}
});

dialog.show();
}

将Activity伪装成对话框：

设置Activity的Dialog风格，在MainActivity里注册下第二个Activity吧
<activity android:name=".testDialog"   android:label="这是一个Activity变成的Dialog"   android:theme="@android:style/Theme.Dialog" ></activity>
