我对android很陌生,但基本上我想设置一个程序,以便当用户点击一个图像视图时,一个点被绘制在他们点击的位置。我已经尝试了很多次,但只是似乎没有能够得到它的工作,并帮助将非常appreciated.So到目前为止,我有安卓绘图
package com.smallbore.smallbore;
import android.app.Activity;
import android.graphics.drawable.ShapeDrawable;
import android.graphics.drawable.shapes.OvalShape;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;
public class targetenter extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.targetenter);
ImageView v = (ImageView) findViewById(R.id.imageView1);
v.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View arg0, MotionEvent arg1) {
TextView t1 = (TextView) findViewById(R.id.textView2);
TextView t2 = (TextView) findViewById(R.id.textView3);
t1.setText("X: "+arg1.getX());
t2.setText("Y: "+arg1.getY());
int x = (int)arg1.getX();
int y = (int)arg1.getY();
int width = 50;
int height = 50;
ShapeDrawable mDrawable = new ShapeDrawable(new OvalShape());
mDrawable.getPaint().setColor(0xff74AC23);
mDrawable.setBounds(x, y, x + width, y + height);
ImageView v = (ImageView) findViewById(R.id.imageView1)
v.setImageDrawable(mDrawable);
return false;
}
});
};
}
完成,虽然我认为这是远远不符合要求 – 2011-02-25 18:40:26
