google在android 6.0系统上增加了权限申请机制,目的是保护用户的隐私,对我个人来说感觉很烦,如果一个app用到了很多权限,那么多弹一个框告诉用户,废话不多说,权限机制分三个步骤
第一步:判断是否申请了权限
第二步:没有申请,则要申请权限
第三步:权限回调处理你的业务,这是在用户同意授权的情况下
为了适配6.0以上的系统,还必须在AndroidManifest.xml文件中权限该添加的还是要添加,现在就以打电话为例,
第一步:判断是否申请了权限api:
ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE)!= PackageManager.PERMISSION_GRANTED
这些权限字符串全都定义在permission内部类中了:
public final class Manifest { public Manifest() { /* compiled code */ } public static final class permission_group { public static final java.lang.String CALENDAR = "android.permission-group.CALENDAR";

可以使用adb shell pm list permissions -d -g命令查看危险权限组

第二步：没有申请就申请权限 api如下:
ActivityCompat.requestPermissions(final l Activity activity,final String[] permissions, final int requestCode)
第一个参数是activity
第二个参数是权限字符串数组
第三个参数是请求码 用户在用户同意授权后，如果一个界面有多个要授权,用这个在权限回调中区分
第三步:权限回调:
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults)
如果用户拒绝了你的权限申请你还可以友好的提示这个权限是干什么的,
使用api:
shouldShowRequestPermissionRationale(@NonNull Activity activity,@NonNull String permission)
这是我打电话的逻辑如何在6.0系统上申请权限:
package com.simple; import android.Manifest; import android.content.Intent; import android.content.pm.PackageManager; import android.net.Uri; import android.support.annotation.NonNull; import android.support.v4.app.ActivityCompat; import android.support.v4.content.ContextCompat; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.Toast; public class MainActivity extends AppCompatActivity { private Button btn_call_phone; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); btn_call_phone = (Button) findViewById(R.id.btn_call_phone); btn_call_phone.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { callPhone(); } }); } private void callPhone() { if(ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE)!= PackageManager.PERMISSION_GRANTED){//表示没有授权 //申请处理 ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.CALL_PHONE},1000); }else{ call(); } } public void call(){ Intent intent = new Intent(); intent.setAction(Intent.ACTION_CALL); Uri data = Uri.parse("tel:" + 110); intent.setData(data); startActivity(intent); // 激活Activity组件 } @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); if(requestCode==1000){ if(grantResults[0]==PackageManager.PERMISSION_GRANTED){ Toast.makeText(this,"权限通过",Toast.LENGTH_SHORT).show(); call(); }else{//权限被拒绝 Toast.makeText(this,"权限被用户拒绝了",Toast.LENGTH_SHORT).show(); } } } } 效果图:
