import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.ImageView;

public class MainActivity extends Activity {

private ImageView img;
private Button btGet;

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

img=(ImageView)findViewById(R.id.img);
btGet=(Button)findViewById(R.id.btGet);

@Override
public void onClick(View v) {
Intent intent=new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, 100);

}
});
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);

if(requestCode==100&&resultCode==this.RESULT_OK){
Uri imgUri= data.getData();
if(imgUri!=null){
img.setImageURI(imgUri);
}

获取当前时间

】第一种方式

DateFormat format=new SimpleDateFormat(“yyyy年MM月dd日”);

format.format(System.currentTimeMillis());

】第二种方式

Calendar calendar=Calendar.getInstance();
calendar.get(Calendar.YEAR);
calendar.get(Calendar.MONTH);
calendar.get(Calendar.DAY_OF_MONTH);

将时间戳转化成时间

SimpleDateFormat sdr = new SimpleDateFormat("yyyy年MM月dd日HH时mm分ss秒");
@SuppressWarnings("unused")
long lcc = Long.valueOf(wintime);
int i = Integer.parseInt(wintime);
String t1 = sdr.format(new Date(i * 1000L));
