如何将捕获的图像显示到新活动？

当我单击一个Button它会打开相机，当我保存它时，它会保存到图库中。 我想在新活动中将该图片显示为ImageView 。

这是我点击相机按钮的代码

 btn2 =(Button)findViewById(R.id.drawer_two); btn2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent upload = new Intent("android.media.action.IMAGE_CAPTURE"); startActivity(upload); } } 

Answer 1

你的主要活动

  public class MainActivity extends ActionBarActivity { private final int requestCode = 20; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Button capturedImageButton = (Button)findViewById(R.id.photo_button); capturedImageButton.setOnClickListener( new View.OnClickListener() { @Override public void onClick(View v) { Intent photoCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(photoCaptureIntent, requestCode); } }); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if(this.requestCode == requestCode && resultCode == RESULT_OK){ Bitmap bitmap = (Bitmap)data.getExtras().get("data"); Intent in1 = new Intent(this, Activity2.class); in1.putExtra("image",bitmap); startActivity(in1); } } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.menu_main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here. The action bar will // automatically handle clicks on the Home/Up button, so long // as you specify a parent activity in AndroidManifest.xml. int id = item.getItemId(); //noinspection SimplifiableIfStatement if (id == R.id.action_settings) { return true; } return super.onOptionsItemSelected(item); } } 

在您的Activity2上，在onCreate方法上编写此代码

 Bundle ex = getIntent().getExtras(); Bitmap bmp2 = ex.getParceable("image"); ImageView result = (ImageView)findViewById(R.Id.imageView1); result.setImageBitmap(bmp); 

Answer 2

使用startActivityForResult()触发Image上传屏幕并使用onActivityResult()获取image数据并在ImageView显示它
