您可以这样使用： this code is only work in android device

main_activity.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <EditText
        android:id="@+id/editText1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:ems="10"
        android:hint="search on Google Play" >

        <requestFocus />
    </EditText>

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="searchData"
        android:text="search" />

</LinearLayout>

活动：

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.new_test);
    }

    public void searchData(View v) {
        EditText ev = (EditText) findViewById(R.id.editText1);
        String search = "market://search?q=";
        search += ev.getText().toString();
        if (v.getId() == R.id.button1) {
            String appPackageName = getPackageName();
            Intent marketIntent = new Intent(Intent.ACTION_VIEW,
                    Uri.parse(search));
            marketIntent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY
                    | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
            startActivity(marketIntent);
        }
    }
}
