使用三方框架

compile 'com.lovedise:permissiongen:0.0.6

//1.请求权限

btn.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

PermissionGen.with(MainActivity.this)

.addRequestCode(100)

.permissions(

Manifest.permission.READ_CONTACTS,

Manifest.permission.RECEIVE_SMS,

Manifest.permission.WRITE_CONTACTS)

.request();

}

});

/**

* 授权成功，后处理的逻辑

*/

@PermissionSuccess(requestCode = 100)

public void doSomething() {

Toast.makeText(this, "Contact permission is granted", Toast.LENGTH_SHORT).show();

}

/**

* 授权失败，后处理的逻辑

*/

@PermissionFail(requestCode = 100)

public void doFailSomething() {

Toast.makeText(this, "Contact permission is not granted", Toast.LENGTH_SHORT).show();

PermissionGen.with(MainActivity.this)

.addRequestCode(100)

.permissions(

Manifest.permission.READ_CONTACTS,

Manifest.permission.RECEIVE_SMS,

Manifest.permission.WRITE_CONTACTS)

.request();

}

@Override

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

PermissionGen.onRequestPermissionsResult(MainActivity.this, requestCode, permissions, grantResults);

}

需要在清单文件中先声明好对应的权限，READ_CONTACTS，RECEIVE_SMS，WRITE_CONTACTS
