我已经通过 java 创建了我的活动 XML,并且还放置了导航抽屉。
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mDrawerLayout = new DrawerLayout(getApplicationContext());
mDrawerLayout.setLayoutParams(new DrawerLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
content_frame = new FrameLayout(getApplicationContext());
content_frame.setLayoutParams(new FrameLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
content_layout = new LinearLayout(getApplicationContext());
content_layout.setOrientation(LinearLayout.VERTICAL);
content_layout.setLayoutParams(new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
content_layout.setBackgroundColor(Color.parseColor("#FFFFFF"));;
tool = new Toolbar(getApplicationContext());
LinearLayout.LayoutParams lp=new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);
tool.setLayoutParams(lp);
tool.setBackgroundColor(Color.parseColor("#00BBD3"));
setSupportActionBar(tool);
tool.setMinimumHeight(getSupportActionBar().getHeight());
content_layout1 = new LinearLayout(getApplicationContext());
content_layout1.setOrientation(LinearLayout.VERTICAL);
content_layout1.setLayoutParams(new DrawerLayout.LayoutParams(320,
LayoutParams.MATCH_PARENT, Gravity.START));
t = new TextView(getApplicationContext());
t.setTextColor(Color.BLACK);
t.setText("XYZ");
ivBottom = new ImageView(getApplicationContext());
LinearLayout.LayoutParams par = new LinearLayout.LayoutParams(50, 50);
par.gravity = Gravity.CENTER_HORIZONTAL;
ivBottom.setLayoutParams(par);
ivBottom.setBackgroundResource(R.drawable.ic_launcher);
mDrawerList = new ListView(getApplicationContext());
mDrawerList.setLayoutParams(new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
content_layout1.setBackgroundColor(Color.BLACK);
content_layout.addView(tool);
content_layout.addView(t);
content_frame.addView(content_layout);
mDrawerLayout.addView(content_frame);
content_layout1.addView(mDrawerList);
content_layout1.addView(ivBottom);
mDrawerLayout.addView(content_layout1);
setContentView(mDrawerLayout);
// Set the adapter for the list view
mDrawerList.setAdapter(new SideAdapter(getApplicationContext(),
menuTitles, menuIcons));
// Set the list's click listener
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, tool,
R.string.action_settings, R.string.action_settings) {
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
invalidateOptionsMenu(); // creates call to
// onPrepareOptionsMenu()
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
invalidateOptionsMenu(); // creates call to
// onPrepareOptionsMenu()
}
};
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
如果我将工具栏高度用于包装内容,这就是我得到的工具栏/操作栏
如您所见,我没有得到操作栏的首选高度。
现在,如果我将高度保持为 100,这是我得到的工具栏/操作栏正如您所见,操作栏切换图标不以内容为中心
我有两个选择:
- 工具栏的大小都达到默认大小
- 或使切换位于中心
我已经尝试了很多东西,但我仍然无法弄清楚。请帮帮我。
