基于Annotation Processor的简单易用的处理Android M运行时权限的库。
部分代码来自PermissionGen, 主要是将其基于运行时注解的实现修改为Annotation Processor的方式,即编译时注解。
project's build.gradle
buildscript {
dependencies {
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
}
}
module's buid.gradle
apply plugin: 'com.neenbedankt.android-apt'
dependencies {
apt 'com.zhy:mpermission-compiler:1.0.0'
compile 'com.zhy:mpermission-api:1.0.0'
}
- 申请权限
MPermissions.requestPermissions(MainActivity.this, REQUECT_CODE_SDCARD, Manifest.permission.WRITE_EXTERNAL_STORAGE);
- 处理权限回调
@Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { MPermissions.onRequestPermissionsResult(this, requestCode, permissions, grantResults); super.onRequestPermissionsResult(requestCode, permissions, grantResults); }
- 是否需要弹出解释
if (!MPermissions.shouldShowRequestPermissionRationale(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE, REQUECT_CODE_SDCARD))
{
MPermissions.requestPermissions(MainActivity.this, REQUECT_CODE_SDCARD, Manifest.permission.WRITE_EXTERNAL_STORAGE);
}
如果需要解释,会自动执行使用@ShowRequestPermissionRationale注解的方法。
授权成功以及失败调用的分支方法通过注解@PermissionGrant和@PermissionDenied进行标识,详细参考下面的例子或者sample。
- in Activity:
public class MainActivity extends AppCompatActivity { private Button mBtnSdcard; private static final int REQUECT_CODE_SDCARD = 2; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mBtnSdcard = (Button) findViewById(R.id.id_btn_sdcard); mBtnSdcard.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { MPermissions.requestPermissions(MainActivity.this, REQUECT_CODE_SDCARD, Manifest.permission.WRITE_EXTERNAL_STORAGE); } }); } @Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { MPermissions.onRequestPermissionsResult(this, requestCode, permissions, grantResults); super.onRequestPermissionsResult(requestCode, permissions, grantResults); } @PermissionGrant(REQUECT_CODE_SDCARD) public void requestSdcardSuccess() { Toast.makeText(this, "GRANT ACCESS SDCARD!", Toast.LENGTH_SHORT).show(); } @PermissionDenied(REQUECT_CODE_SDCARD) public void requestSdcardFailed() { Toast.makeText(this, "DENY ACCESS SDCARD!", Toast.LENGTH_SHORT).show(); } }
- in Fragment:
public class TestFragment extends Fragment { @Nullable @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_test, container, false); } @Override public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { view.findViewById(R.id.id_btn_contact).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { MPermissions.requestPermissions(TestFragment.this, 4, Manifest.permission.WRITE_CONTACTS); } }); } @PermissionGrant(4) public void requestContactSuccess() { Toast.makeText(getActivity(), "GRANT ACCESS CONTACTS!", Toast.LENGTH_SHORT).show(); } @PermissionDenied(4) public void requestContactFailed() { Toast.makeText(getActivity(), "DENY ACCESS CONTACTS!", Toast.LENGTH_SHORT).show(); } @Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { MPermissions.onRequestPermissionsResult(this, requestCode, permissions, grantResults); super.onRequestPermissionsResult(requestCode, permissions, grantResults); } }
