Android_动态权限管理的解决方式

(1)普通权限

(2)许可权限

(1).ContextCompat.checkSelfPermission()

(2).ActivityCompat.requestPermissions()

(3).AppCompatActivity.onRequestPermissionsResult()

public class BaseActivity extends AppCompatActivity {
private Map<Integer, Runnable> allowablePermissionRunnables = new HashMap<>();
private Map<Integer, Runnable> disallowablePermissionRunnables = new HashMap<>();

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}

/**
* 请求权限
* @param id 请求授权的id 唯一标识就可以
* @param permission 请求的权限
* @param allowableRunnable 允许授权后的操作
* @param disallowableRunnable 禁止权限后的操作
*/
protected void requestPermission(int id, String permission, Runnable allowableRunnable, Runnable disallowableRunnable) {
if (allowableRunnable == null) {
throw new IllegalArgumentException("allowableRunnable == null");
}

allowablePermissionRunnables.put(id, allowableRunnable);
if (disallowableRunnable != null) {
disallowablePermissionRunnables.put(id, disallowableRunnable);
}

//版本号推断
if (Build.VERSION.SDK_INT >= 23) {
//降低是否拥有权限
int checkCallPhonePermission = ContextCompat.checkSelfPermission(getApplicationContext(), permission);
if (checkCallPhonePermission != PackageManager.PERMISSION_GRANTED) {
//弹出对话框接收权限
ActivityCompat.requestPermissions(BaseActivity.this, new String[]{permission}, id);
return;
} else {
allowableRunnable.run();
}
} else {
allowableRunnable.run();
}
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);

if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Runnable allowRun = allowablePermissionRunnables.get(requestCode);
allowRun.run();
} else {
Runnable disallowRun = disallowablePermissionRunnables.get(requestCode);
disallowRun.run();
}
}
}
