1. 按按钮button拍照显示到ImageView中

public class MainActivity extends Activity {private ImageView iv;private File file ;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);iv = (ImageView) findViewById(R.id.iv);}public void click(View view) {Intent intent = new Intent();// 指定拍照的意图。intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);file =  new File(Environment.getExternalStorageDirectory(),System.currentTimeMillis()+".jpg");intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file)); // 指定保存文件的路径startActivityForResult(intent, 100);}        //调用activity后返回@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {if(requestCode==100){iv.setImageURI(Uri.fromFile(file));}super.onActivityResult(requestCode, resultCode, data);}}
