DrawerLayout 用法，先從佈局檔案看，如下所示 “

需要注意的是：用ToolBar替換ActionBar的時候，必須呼叫這個方法supportRequestWindowFeature(Window.FEATURE_NO_TITLE);否則會報錯

package com.example.bluetooth; import android.support.v7.app.ActionBarDrawerToggle; import android.support.v7.widget.Toolbar; import android.support.v4.widget.DrawerLayout; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log; import android.view.View; import android.view.Window; import android.widget.RelativeLayout;

public class BitmapActivity extends AppCompatActivity {

private DrawerLayout drawerLayout;
private RelativeLayout mainLeft;
private RelativeLayout mainRight;
private Toolbar toolbar;
private ActionBarDrawerToggle drawerToggle;
public static String TAG = "BitmapActivity lgj";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_bitmap);
    initView();
    //將actionBar替換成toolbar
    setSupportActionBar(toolbar);
    initEvent();

}

private void initEvent() {
    drawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar, R.string.drawerOpen,R.string.drawerClose);
    //同步狀態
    drawerToggle.syncState();
    //給側滑空間設定監聽
 

// drawerLayout.setDrawerListener(drawerToggle); drawerLayout.setDrawerListener(new DrawerLayout.DrawerListener() { @Override public void onDrawerSlide(View drawerView, float slideOffset) { View content = drawerLayout.getChildAt(0); //側滑的view View menu = drawerView; Log.i(TAG,slideOffset+”“); //縮放側滑選單從0.7到 -> 1 float scaleLeft = (float) (0.7 + 0.3*slideOffset); //放大側滑面板 menu.setScaleX(scaleLeft); menu.setScaleY(scaleLeft); //content 放大從1到0.7 float scaleContent = (float) (1-0.3*slideOffset); content.setScaleX(scaleContent); content.setScaleY(scaleContent); //content平移從0到1， int id = menu.getId(); if (id == R.id.main_left_drawer_layout){ content.setTranslationX(menu.getMeasuredWidth()*slideOffset); }else { content.setTranslationX(-menu.getMeasuredWidth()*slideOffset); } }

        @Override
        public void onDrawerOpened(View drawerView) {
        }

        @Override
        public void onDrawerClosed(View drawerView) {
        }

        @Override
        public void onDrawerStateChanged(int newState) {
        }
    });
}    //左邊選單開關事件
public void openLeftLayout(View view) {
    if (drawerLayout.isDrawerOpen(mainLeft)) {
        drawerLayout.closeDrawer(mainLeft);
    } else {
        drawerLayout.openDrawer(mainLeft);
    }
}
// 右邊選單開關事件
public void openRightLayout(View view) {
    if (drawerLayout.isDrawerOpen(mainRight)) {
        drawerLayout.closeDrawer(mainRight);
    } else {
        drawerLayout.openDrawer(mainRight);
    }
}
private void initView() {
    toolbar = (Toolbar) findViewById(R.id.toolBar);
    drawerLayout = (DrawerLayout) findViewById(R.id.main_drawer_layout);
    mainLeft = (RelativeLayout) findViewById(R.id.main_left_drawer_layout);
    mainRight = (RelativeLayout) findViewById(R.id.main_right_drawer_layout);
}

}
