Android屏幕适配之状态栏导航栏半透明、全透明（5.0以上去阴影），方法多样
GitHub
APK
使用方法
将libray模块复制到项目中,或者直接在build.gradle中依赖:
allprojects {
repositories {
maven { url 'https://jitpack.io' }
}
}dependencies {
compile 'com.github.AnJiaoDe:StatusNavigationTransparent:V1.1.2'
}注意：如果sync报错，是因为和com.android.tools.build:gradle 3.0有关，
可以改将compile改为implementation 或者api 
注意：状态栏半透明和全透明只有4.4以上才能实现，5.0以上才能去阴影
本文只描述在activity中如何使用，fragment中使用方法类似，可以实现
首先创建全局theme
然后创建BaseActivity实现StatusBar全透明
public abstract class BaseActivity extends AppCompatActivity implements View.OnClickListener {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
StatusNavUtils.setStatusBarColor(this,0x00000000);
}
public void startAppcompatActivity(Class cls) {
startActivity(new Intent(this, cls));
}
}
1. StatusBar半透明
1.1 StatusBar半透明用StatusBarView实现(4.4以上有效)
public class Status1Activity extends BaseActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_trans_status_bar);
}
@Override
public void onClick(View v) {
}
}
1.2 StatusBar半透明用setStatusBarColor实现(5.0以上有效)
public class Status2Activity extends BaseActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_status2);
StatusNavUtils.setStatusBarColor(this,0x33000000);
}
@Override
public void onClick(View v) {
}
}
2. StatusBar全透明
2.1 StatusBar全透明用fitSystemWindows实现(4.4以上有效)
public class Status3Activity extends BaseActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_status3);
}
@Override
public void onClick(View v) {
}
}
2.2 StatusBar全透明用StatusBarView实现(4.4以上有效)
public class Status4Activity extends BaseActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_status4);
}
@Override
public void onClick(View v) {
}
}
3. StatusBar透明于图片之上
3.1 StatusBar半透明于图片之上用setStatusBarColor实现(5.0以上有效)
public class Status5Activity extends BaseActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_status5);
StatusNavUtils.setStatusBarColor(this,0x33000000);
}
@Override
public void onClick(View v) {
}
}
3.2 StatusBar全透明于图片之上(4.4以上有效)
public class Status6Activity extends BaseActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_status6);
}
@Override
public void onClick(View v) {
}
}
3. NavigationBar透明
3.1 NavigationBar半透明用setNavigationBarColor实现(5.0以上有效)
public class Navigation1Activity extends BaseActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_status7);
StatusNavUtils.setNavigationBarColor(this,0x33000000);
}
@Override
public void onClick(View v) {
}
}
3.2 NavigationBar全透明(4.4以上有效)
public class Navigation2Activity extends BaseActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation2);
StatusNavUtils.setNavigationBarColor(this,0x00000000);
}
@Override
public void onClick(View v) {
}
}
