添加虛化層
使用網(wǎng)絡(luò)第三方包
1.1buid.gradle導(dǎo)入包
.gradle
包
1.2使用
<io.alterac.blurkit.BlurLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:blk_fps="0"
app:blk_blurRadius="5"
/>
1.3基本方法
fps:虛化第幾幀
blurRadius：虛化程度
- 焦點(diǎn)
當(dāng)有控件獲得焦點(diǎn)focus ?動彈出鍵盤
1.點(diǎn)擊軟鍵盤的enter鍵 ?動收回鍵盤
2.代碼控制 InputMethodManager
requestFocus
showSoftInput:顯示鍵盤 必須先讓這個(gè)view成為焦點(diǎn)requestFocus
hideSoftInputFromWindow 隱藏鍵盤
@Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN){
//隱藏鍵盤
//1.獲取系統(tǒng)輸?的管理器
InputMethodManager inputManager =
(InputMethodManager)
getSystemService(INPUT_METHOD_SERVICE);
//2.隱藏鍵盤
inputManager.hideSoftInputFromWindow(user.getWindowToken(),
0);
//3.取消焦點(diǎn)
View focusView = getCurrentFocus();
if (focusView != null) {
focusView.clearFocus(); //取消焦點(diǎn)
}
//getCurrentFocus().clearFocus();
//focusView.requestFocus();//請求焦點(diǎn)
}
return true;
