你應(yīng)該創(chuàng)建具有有限寬度和高度的透明 Activity，而不是彈出對(duì)話框。 這樣它就像對(duì)話框，然后你可以打開(kāi)另一個(gè) Activity 并使用 intent.putExtra() 傳遞值

通過(guò)這種方式，你還可以使用 startActivityForResult() 和 onActivityResult() 。public class PopupWindowActivity extends Activity {

PopupWindow popwindow;

Button btnpopupopener,btnOpenActicivt;

TextView tv_result;

final static int POPRESULTcode=1;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_popup_window);

btnpopupopener=(Button)findViewById(R.id.btnpopupopen);

btnpopupopener.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

//TODO Auto-generated method stub

LayoutInflater inflator= (LayoutInflater)PopupWindowActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

LinearLayout vi=(LinearLayout)inflator.inflate(R.layout.layout_popup_content, null);

btnOpenActicivt= (Button)vi.findViewById(R.id.btnOpenActivity);

tv_result=(TextView)vi.findViewById(R.id.tv_result);

popwindow = new PopupWindow(vi, LinearLayout.LayoutParams.MATCH_PARENT,

LinearLayout.LayoutParams.WRAP_CONTENT);

popwindow.setContentView(vi);

btnOpenActicivt.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

//TODO Auto-generated method stub

Intent in= new Intent(PopupWindowActivity.this, SampleResultActivity.class);

startActivityForResult(in, POPRESULTcode);

}

});

popwindow.showAsDropDown(btnpopupopener);

}

});

}

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

//TODO Auto-generated method stub

super.onActivityResult(requestCode, resultCode, data);

switch(resultCode){

case POPRESULTcode:

Log.i("Result"," Getting Message From Result Activity");

tv_result.setText(data.getExtras().getString("resultstring"));

popwindow.showAsDropDown(btnpopupopener);

break;

}

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

//Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.popup_window, menu);

return true;

}

public class SampleResultActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_sample_result);

Intent in= new Intent(getApplicationContext(), PopupWindowActivity.class);

in.putExtra("resultstring","Sending Sample String as Data");

setResult(1, in);

finish();

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

//Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.sample_result, menu);

return true;

}
