我的活动应显示带有一些选项的自定义对话框,并且根据选项应提交布局更改而不关闭对话框。可能吗?有什么想法吗?

试试这个, 首先制作
custom.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/cat" />
<TextView
android:id="@+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="20dp"
android:text="Hey there i am cat"
android:textAppearance="?android:attr/textAppearanceLarge" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</RelativeLayout>
然后在activity_main.xml中添加以下代码,
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="Button" />`</RelativeLayout>`
然后在MainActivity.java中,
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button B = (Button) findViewById(R.id.button1);
B.setOnClickListener(new OnClickListener(){
public void onClick(View arg0) {
Dialog d = new Dialog(MainActivity.this);
d.setContentView(R.layout.dialog);
d.setTitle("This is custom dialog box");
d.show();
}
});
}
