我对android编程很新，我需要在android中使用SlidingPaneLayout帮助解决这个问题。我会附上一份日志。这是我的代码：
package com.anshikka.datagushalpha;
import android.os.Bundle;
import android.app.Activity;
import android.support.v4.app.FragmentActivity;
import android.support.v4.widget.SlidingPaneLayout;
import android.view.View;
public class MainActivity extends FragmentActivity {
SlidingPaneLayout pane;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pane = (SlidingPaneLayout) findViewById(R.id.sp);
pane.setPanelSlideListener(new PaneListener());
if (!pane.isSlideable()) {
getFragmentManager().findFragmentById(R.id.leftpane).setHasOptionsMenu(false);
getFragmentManager().findFragmentById(R.id.rightpane).setHasOptionsMenu(true);
}
}
private class PaneListener extends FragmentActivity implements SlidingPaneLayout.PanelSlideLi stener {
@Override
public void onPanelClosed(View view) {
System.out.println("Panel closed");
getSupportFragmentManager().findFragmentById(R.id.leftpane).setHasOptionsMenu(false);
getSupportFragmentManager().findFragmentById(R.id.rightpane).setHasOptionsMenu(true);
}
@Override
public void onPanelOpened(View view) {
System.out.println("Panel opened");
getSupportFragmentManager().findFragmentById(R.id.leftpane).setHasOptionsMenu(true);
getSupportFragmentManager().findFragmentById(R.id.rightpane).setHasOptionsMenu(false);
}
@Override
public void onPanelSlide(View view, float arg1) {
System.out.println("Panel sliding");
}
}
}
//XML File for SlidingPaneLayout
<android.support.v4.widget.SlidingPaneLayout
