Android6.0權限擷取方法封裝

項目中很多操作需要事先進行危險權限的判斷和擷取，本人在Android項目開發中封裝了一個擷取Android6.0以上系統危險權限的擷取的方法，希望能給大家帶來幫助。

首先定義一個接口，裡面有兩個方法。

public interface AccreditListener {
    void onAccreditSucceed(); //權限擷取成功
    void onAccreditFailure(); //權限擷取失敗
}
           

然後，定義一個activity基類，可供需要工程中的activity繼承。

public class AppBaseActivity extends AppCompatActivity {

    public int mRequestCode;
    public int mPermissionRequestCount;
    private AccreditListener mAccreditListener;

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

    /**
     * android6.0權限處理
     *
     * @param context
     * @param permissionNames
     * @param requestCode
     */
    public void requestPermission(Context context, String[] permissionNames, int requestCode, AccreditListener accreditListener) {
        if (permissionNames == null || permissionNames.length < ) {
            return;
        }
        mRequestCode = requestCode;
        mPermissionRequestCount = permissionNames.length;
        mAccreditListener = accreditListener;
        boolean isPermitted = true;
        for (String permissionName : permissionNames) {
            if (PackageManager.PERMISSION_GRANTED != ContextCompat.checkSelfPermission(context, permissionName)) {
                isPermitted = false;
            }
        }
        if (isPermitted) {
            mAccreditListener.onAccreditSucceed();
        } else {
            ActivityCompat.requestPermissions((Activity) context, permissionNames, requestCode);
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        if (requestCode == mRequestCode && mPermissionRequestCount > ) {
            boolean isPermitted = true;
            for (int i = ; i < mPermissionRequestCount; i++) {
                if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {
                    isPermitted = false;
                }
            }
            if (isPermitted) {
                mAccreditListener.onAccreditSucceed();
            } else {
                mAccreditListener.onAccreditFailure();
            }
        }
    }
           

後面可以在需要的地方随意調用了，比如：

mMicrophone.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                requestPermission(
                        ContactSearchActivity.this,
                        new String[]{
                                Manifest.permission.RECORD_AUDIO,
                                Manifest.permission.READ_EXTERNAL_STORAGE,
                                Manifest.permission.WRITE_EXTERNAL_STORAGE},
                        , new AccreditListener() {
                            @Override
                            public void onAccreditSucceed() {
                                Log.i(TAG,"權限擷取成功！");
                            }

                            @Override
                            public void onAccreditFailure() {
                                Log.i(TAG,"權限擷取失敗！");
                            }
                        });
            }
        });
