PoopubWindow,能用showAsDropDown,就是用不了showAtLocation,（如图）

就是设置不了Gravity，真是日了狗了，不知道是倒入类错了，还是其他其他原因


完整代码如下：
错的在倒数几行

package com.example.zhuwen.model_popubwindow;

import android.app.Activity;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.widget.EditText;
import android.view.View;
import android.widget.PopupWindow;
import android.widget.TextView;
import android.view.View.OnClickListener;
import android.widget.Toast;

public class MainActivity extends Activity{

    private PopupWindow popupWindow;
    private View contentView;
    private TextView tx_pop;
    private TextView tx_test;
    private EditText ed_test;
    int width=0,height=0;

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

        tx_pop = (TextView)findViewById(R.id.tx_pop);
        tx_test = (TextView)findViewById(R.id.tx_test);
        ed_test = (EditText)findViewById(R.id.ed_test);

        //get the width and height of screen
        final DisplayMetrics metric = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(metric);
        width = metric.widthPixels/2;
        height = metric.heightPixels/2;

        tx_test.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getApplicationContext(),"Can Touch",
                        Toast.LENGTH_SHORT).show();
            }
        });

        tx_pop.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                get_pop();
            }
        });

    }

    public void get_pop() {

        contentView = getLayoutInflater().inflate(R.layout.pop_win, null);
        popupWindow = new PopupWindow(contentView, 300,
                200);
        popupWindow.setContentView(contentView);
        //.setBackgroundDrawable(getResources().getDrawable(R.drawable.search_label_click));
        //.setBackgroundColor(Color.parseColor("#F5F5DC"));
        //.setBackgroundColor(Color.GRAY);
        popupWindow.setBackgroundDrawable(getResources().getDrawable(R.drawable.test));
        //set "true" ,then you can enter something
        //set "true",a popwin will disappear when you touch the outside of the popwin
        popupWindow.setFocusable(true);
        //decided the location of a popwin
        popupWindow.showAtLocation(R.id.tx_pop,Gravity.LEFT, 0, 0);
        //the command to close a popwin
        //popupWindow.dismiss();

    }
}
