Android 几行代码解决6.0以上权限适配问题
GitHub APK 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) { } } 源码： public abstract class PermissionActivity extends AppCompatActivity implements View.OnClickListener { private String toast_perm_refuse,dialog_perm_refuse_noask; private OnPermissionRequestListener onPermissionHaveListener; public <T extends View> T getViewByID(@IdRes int id) { return (T) findViewById(id); } //?????????????????????????????????????????????????????????????????????? public String nullToString(Object object) { return object == null ?
