我正在使用这个
link实现滑动菜单.现在,如果我在onCreate()方法中使用此代码,它的工作正常.
我的简单问题是如何在按钮的点击事件上打开滑块？
我使用以下代码.
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final SlidingMenu menu = new SlidingMenu(this);
Button mButton = (Button) findViewById(R.id.slidingMenu);
mButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
menu.setMode(SlidingMenu.RIGHT);
menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
menu.setBehindOffsetRes(R.dimen.slidingmenu_offset);
menu.setFadeDegree(0.5f);
menu.attachToActivity(MainActivity.this,SlidingMenu.SLIDING_CONTENT);
menu.setMenu(R.layout.activity_menu);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main,menu);
return true;
}
}
解决方法
您应该在单击侦听器之前设置菜单.在您的代码段中,每次单击按钮时都会设置并附加菜单.但是,您应该只显示菜单而不是在点击时附加它.
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final SlidingMenu menu = new SlidingMenu(this);
menu.setMode(SlidingMenu.RIGHT);
menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
menu.setBehindOffsetRes(R.dimen.slidingmenu_offset);
menu.setFadeDegree(0.5f);
menu.attachToActivity(MainActivity.this,SlidingMenu.SLIDING_CONTENT);
menu.setMenu(R.layout.activity_menu);
Button mButton = (Button) findViewById(R.id.slidingMenu);
mButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
menu.showMenu();
//or
//menu.toggle();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main,menu);
return true;
}
}
