沉浸式状态栏

1、全沉浸式自定义颜色

//判断当前SDK版本号，如果是4.4以上，就是支持沉浸式状态栏的

if(Build.VERSION.SDK_INT>= Build.VERSION_CODES.LOLLIPOP) {

getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

getWindow().setStatusBarColor(getApplicationContext().getResources().getColor(R.color.deepblue));

}

Window window = getWindow();

if(translucentStatusBar()) {

//设置状态栏全透明

if(Build.VERSION.SDK_INT>= Build.VERSION_CODES.LOLLIPOP) {

window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN| View.SYSTEM_UI_FLAG_LAYOUT_STABLE);

window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

window.setStatusBarColor(Color.TRANSPARENT);

}else if(Build.VERSION.SDK_INT>= Build.VERSION_CODES.KITKAT) {

getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

}

return;

}

//沉浸式状态栏

if(Build.VERSION.SDK_INT>= Build.VERSION_CODES.LOLLIPOP) {

//5.0以上使用原生方法

window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

window.setStatusBarColor(setStatusBarColor());

}else if(Build.VERSION.SDK_INT>= Build.VERSION_CODES.KITKAT) {

//4.4-5.0使用三方工具类，有些4.4的手机有问题，这里为演示方便，不使用沉浸式

//            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

SystemBarTintManager tintManager =newSystemBarTintManager(this);

tintManager.setStatusBarTintEnabled(true);

tintManager.setStatusBarTintColor(setStatusBarColor());

}

全屏

// 设置全屏模式

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

// 去除标题栏

requestWindowFeature(Window.FEATURE_NO_TITLE);

2、修改BACK键为HOME键

public boolean onKeyDown(int keyCode, KeyEvent event) {

if (keyCode == KeyEvent.KEYCODE_BACK) {

Intent intent = new Intent(Intent.ACTION_MAIN);

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

intent.addCategory(Intent.CATEGORY_HOME);

startActivity(intent);

return true;

}return super.onKeyDown(keyCode, event);}

3、判断点击两次返回键退出系统

public voidbackSystem() {

TimerTask task =newTimerTask() {

@Override

public voidrun() {

isExit=false;

isHasTask=true;

}

};

if(!isExit) {

isExit=true;

Toast.makeText(mView,"再按一次退出APOS", Toast.LENGTH_LONG).show();

exitTime= System.currentTimeMillis();

if(!isHasTask) {

tExit.schedule(task,2000);

}

}else{

longtemp = System.currentTimeMillis() -exitTime;

if(temp <2000) {

exitSystem();

}else{

Toast.makeText(mView,"再按一次退出APOS", Toast.LENGTH_LONG).show();

isExit=false;

isHasTask=false;

mView.onBackPressed();

}}}

3、格式化时间

SimpleDateFormat time = new SimpleDateFormat("MM/dd HH:mm:ss");

4、数据类型大小

数据类型大小

5、安装软件

Intent intent =newIntent(Intent.ACTION_VIEW);

intent.setDataAndType(Uri.fromFile(newFile(APKpath)),"application/vnd.android.package-archive");

startActivity(intent);

6、卸载软件

Uri uri = Uri.parse("package:包名");

Intent intent = new Intent(Intent.ACTION_DELETE,uri);

startActivity(intent);

7、自定义Notification

一定要设置smallIcon否则会报错
