andoid 6.0权限下调用系统电话call

首先在代码中添加call权限

android:name="android.permission.CALL_PHONE" />

以下是代码正文

package peng.com.myapplication.call;

import android.Manifest;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.os.Build;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;

import peng.com.myapplication.R;

public class Main2Activity extends AppCompatActivity implements View.OnClickListener {
    private String[] perms = {Manifest.permission.CALL_PHONE};
    private final int PERMS_REQUEST_CODE = 200;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);

        findViewById(R.id.btn_call_phone).setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        if (v.getId() == R.id.btn_call_phone) {//获取拨打电话的权限
            if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP_MR1) {//Android 6.0以上版本需要获取权限
                requestPermissions(perms,PERMS_REQUEST_CODE);//请求权限
            } else {
                callPhone();
            }
        }
    }

    /**
     * 获取权限回调方法
     * @param permsRequestCode
     * @param permissions
     * @param grantResults
     */
    @Override
    public void onRequestPermissionsResult(int permsRequestCode, String[] permissions, int[] grantResults) {
        switch (permsRequestCode) {
            case PERMS_REQUEST_CODE:
                boolean storageAccepted = grantResults[0] == PackageManager.PERMISSION_GRANTED;
                if (storageAccepted) {
                    callPhone();
                } else {
                    Log.i("MainActivity", "没有权限操作这个请求");
                }
                break;

        }
    }

    //拨打电话
    private void callPhone() {
        //检查拨打电话权限
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
            Intent intent = new Intent(Intent.ACTION_CALL);
            intent.setData(Uri.parse("tel:" + "15171476706"));
            startActivity(intent);
        }
    }
}
