一、多權(quán)限申請(qǐng)

①在oncreat(）方法中寫此方法

/**
 * 6.0之后的動(dòng)態(tài)申請(qǐng)權(quán)限
 */
checkRequiredPermission(LoginActivity.this);

②

/**
 * 檢查權(quán)限
 * @param activity
 */
private void checkRequiredPermission(final Activity activity) {
    for (String permission : permissionsArray) {
        if (ContextCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED) {
            permissionsList.add(permission);
        }
    }
    if (permissionsList.size()!=0){
        ActivityCompat.requestPermissions(activity, permissionsList.toArray(new String[permissionsList.size()]), REQUEST_CODE_ASK_PERMISSIONS);
    }

}

③實(shí)現(xiàn)回調(diào)

//動(dòng)態(tài)申請(qǐng)權(quán)限的返回值
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case REQUEST_CODE_ASK_PERMISSIONS:
            for (int i = 0; i < permissions.length; i++) {
                if (grantResults[i] == PackageManager.PERMISSION_GRANTED) {
                    Toast.makeText(LoginActivity.this, "權(quán)限開啟" + permissions[i], Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(LoginActivity.this, "權(quán)限禁止" + permissions[i], Toast.LENGTH_SHORT).show();
                }
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

二、單權(quán)限申請(qǐng)（也可以直接用多權(quán)限申請(qǐng)的方法，在里面只寫一個(gè)權(quán)限）：

①

第一步判斷時(shí)候授權(quán)。

if (Build.VERSION.SDK_INT >= 23) { int checkCallPhonePermission = ContextCompat.checkSelfPermission(FoodActivity.this, Manifest.permission.CAMERA);
??????????????????????? if(checkCallPhonePermission != PackageManager.PERMISSION_GRANTED){
??????????????????????????? ActivityCompat.requestPermissions(FoodActivity.this,new String[]{Manifest.permission.CAMERA},222);
??????????????????????????? return;
??????????????????????? }else{

??????????????????????????? openCamra();//調(diào)用具體方法
??????????????????????? }
??????????????????? } else {

??????????????????????? openCamra();//調(diào)用具體方法

}

②寫回調(diào)

@Override
??? public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
??????? switch (requestCode) {
??????? //就像onActivityResult一樣這個(gè)地方就是判斷你是從哪來(lái)的。
??????????? case 222:
??????????????? if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
??????????????????? // Permission Granted
??????????????????? openCamra();
??????????????? } else {
??????????????????? // Permission Denied
??????????????????? Toast.makeText(FoodActivity.this, "很遺憾你把相機(jī)權(quán)限禁用了。請(qǐng)務(wù)必開啟相機(jī)權(quán)限享受我們提供的服務(wù)吧。", Toast.LENGTH_SHORT)
??????????????????????????? .show();
??????????????? }
??????????????? break;
??????????? default:
??????????????? super.onRequestPermissionsResult(requestCode, permissions, grantResults);
??????? }
??? }
