关于Android6.0之后的权限问题 _权限问题

逆水行舟用力撑，一篙松劲退千寻。这篇文章主要讲述关于Android6.0之后的权限问题相关的知识，希望能为你提供帮助。

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‘ }

dependencise：一个就行了：compile ‘com.zhy:mpermission-api:1.0.0‘

使用方法

final int REQUECT_CODE_READ_SMS = 100;

MPermissions.requestPermissions(AnayseSmsUploadActivity.this, REQUECT_CODE_READ_SMS, Manifest.permission.READ_SMS);

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

//请求成功
@PermissionGrant(REQUECT_CODE_READ_SMS)
public void requestSdcardSuccess() {

}

//请求失败

@PermissionDenied(REQUECT_CODE_READ_SMS)
public void requestSdcardFailed() {
finash();
}

MPermissions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。
引入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‘ }

使用

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。
例子

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); } }
