Android 几行代码解决6.0以上权限适配问题
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:Permission:V1.0.0'
}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
Android 6.0以上，危险权限必须经过动态请求，危险权限分组图
1.全部允许
2.拒绝
3.拒绝
4.用户拒绝并且选中了不再询问，弹窗让用户去授权
5.用户同意了授权，闲的难受去关闭了授权
使用方法:
public class MainActivity extends PermissionActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
checkPermissionCAMERA(new OnPermissionRequestListener() {
@Override
public void onPermissionHave() {
showToast("用户同意了相机权限");
checkPermissionWRITE_EXTERNAL_STORAGE(new OnPermissionRequestListener() {
@Override
public void onPermissionHave() {
showToast("用户同意了存储权限,可以执行拍照操作了");
}
@Override
public void onPermissionRefuse() {
showToast("用户拒绝了存储权限");
}
@Override
public void onPermissionRefuseNoAsk() {
showToast("用户拒绝了存储权限并且选中了不再询问");
}
});
}
@Override
public void onPermissionRefuse() {
showToast("用户拒绝了相机权限");
}
@Override
public void onPermissionRefuseNoAsk() {
showToast("用户拒绝了相机权限并且选中了不再询问");
}
});
}
});
//或者
// checkPermission(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
// "存储权限已被禁用","拍照功能必须打开存储权限，否则无法使用", new OnPermissionRequestListener() {
//
// @Override
// public void onPermissionHave() {
//
// showToast("用户同意了存储权限");
//
//
// }
//
// @Override
// public void onPermissionRefuse() {
// showToast("用户拒绝了存储权限");
//
// }
//
// @Override
// public void onPermissionRefuseNoAsk() {
// showToast("用户拒绝了存储权限并且选中了不再询问");
//
// }
// });
}
@Override
public void onClick(View v) {
}
}
