在Android的原因透明状态栏隐藏键盘编辑
I make an Android application, following Google's material design guidelines.
So, I've implemented the latest support libraries (my min Sdk value is 14)
Now, I face to a problem : I've made the status bar transparent, with custom ToolBar (defined in a XML file). Everything works well, except that FloatingActionButton (from ) skips XML's defined layout margin. Idem, one of my app's UI uses TextView to login the user : once focused, they're hidden by the soft keyboard.
These two problems came after replacing the main style from "AppCompat.DarkActionBar" to "AppCompat.NoActionBar" (and with item "android:windowTranslucentStatus" set to "true").
I tried to use windowSoftInputMode in my manifest with "adjustPan|adjustResize", but nothing change. Adding "ScrollView" to the layout with "EditText" inside doesn't solve my problem neither.
My english is bad, and I know that pictures are better than words, so here is what I want to do and what's happening :

Any ideas ? Thanks for reading !
EDIT : I solved my problem with the FloatingButton, just need to add this line to the component's XML declaration :
android:layout_alignParentBottom="true"
The only problem now is the keyboard that hides EditText.
Here is my code :

In my MainActivity, I have the DrawerLayout and some codelines not in relationship with the Toolbar / layout, except for :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
toolbar = (Toolbar) findViewById(R.id.tool_bar);
toolbar.setPadding(0, getStatusBarHeight(), 0, 0);
setSupportActionBar(toolbar);
// enabling action bar app icon and behaving it as toggle button
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setIcon(new ColorDrawable(getResources().getColor(android.R.color.transparent)));
// A method to find height of the status bar
// Source : an Stackoverflow's answer
public int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId & 0) {
result = getResources().getDimensionPixelSize(resourceId);
Ok, finally found a solution. Using this code in Fragment solves everything.
getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN | WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
By the way, use AppCompatActivity instead of ActionBarActivity (support V7), I'm not sure it changes something, but just in case ...

日46分27秒
& 2017 内容协议先说说我的使用场景：
我写了一个activity，使用了actionbar.
在这个activity中，有fragment，默认先打开一个 homeFragment,点击某个按钮会进入 detailFragment.
当启动detailFragment 时，问题出现了：
我希望在detailFragment 打开时，actionbar出现 返回的箭头 &"&" .
于是我在onStart中写下：
public void onStart() {
super.onStart();
ActionBar actionBar = getActivity().getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setIcon(
new ColorDrawable(getResources().getColor(android.R.color.transparent))); //在这里，我把图标改成透明色了
actionbar上有了返回按钮，我希望在点击该按钮关闭 自己这个fragment
于是我监听onOptionsItemSelected事件
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
getActivity().getFragmentManager().popBackStack();
return false;
return super.onOptionsItemSelected(item);
但是，点击返回按钮后，将无法工作。你会发现&onOptionsItemSelected 不会被调用。
解决方法：在 onCreate时调用&setHasOptionsMenu(true);
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
处理homeFragment的actionbar 图标状态
由于我有了一个homeFragment,这将是我的主fragment,我希望在这个homeFragment被覆盖时，由覆盖他的fragment控制actionbar （比如变成有返回图标的样子），当覆盖他的fragment关闭，homeFragment重新出现时，还要变成原先的样子（有图标，无返回按钮）。
要达到这点，这就要获得 actionbar的图标，get 它的 Icon。
代码如下：
Drawable actionbar_lastHomeI
public void onStart() { //重新显示时，再设置会图标
super.onStart();
ActionBar actionBar = getActivity().getActionBar();
actionBar.setDisplayHomeAsUpEnabled(false);
if (actionbar_lastHomeIcon != null)
actionBar.setIcon(actionbar_lastHomeIcon);
public void onPause() {//被覆盖时，记录下 图标
super.onPause();
ImageView imageView = (ImageView) getActivity().findViewById(
android.R.id.home);
actionbar_lastHomeIcon = imageView.getDrawable();
