MainActivity.java

public class MainActivity extends AppCompatActivity {private ListView listCalls;private List<Map<String, Object>> mapList;private static final int REQUEST_CODE = 0;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);onShowCallLog();}public void initView() {listCalls = (ListView) super.findViewById(R.id.call_list);SimpleAdapter simpleAdapter = new SimpleAdapter(this,mapList,R.layout.call_item,new String[]{CallLog.Calls.NUMBER, CallLog.Calls.DATE},new int[]{R.id.call_mobile, R.id.call_date});listCalls.setAdapter(simpleAdapter);}private void initDate() {ContentResolver contentResolver = getContentResolver();Cursor cursor = contentResolver.query(CallLog.Calls.CONTENT_URI,new String[]{CallLog.Calls.NUMBER, CallLog.Calls.DATE},null, null, null);mapList = new ArrayList<>();SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd");while (cursor.moveToNext()) {Map<String, Object> stringObjectMap = new HashMap<>();stringObjectMap.put(CallLog.Calls.NUMBER, cursor.getString(0));stringObjectMap.put(CallLog.Calls.DATE, simpleDateFormat.format(new Date(cursor.getLong(1))));mapList.add(stringObjectMap);}cursor.close();}private void onShowCallLog() {int checkCALL_LOGPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CALL_LOG);if (checkCALL_LOGPermission != PackageManager.PERMISSION_GRANTED) {ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_CALL_LOG}, REQUEST_CODE);} else {initDate();initView();}}@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {if (requestCode == REQUEST_CODE) {if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {Toast.makeText(this, "获取权限成功", Toast.LENGTH_SHORT).show();initDate();initView();} else {Toast.makeText(this, "获取权限失败", Toast.LENGTH_SHORT).show();this.finish();}} else {super.onRequestPermissionsResult(requestCode, permissions, grantResults);}}
