android擷取螢幕像素思路及代碼

複製代碼 代碼如下:<SPAN style="FONT-SIZE: 18px">private void alertScreenDialog() {
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
String optStr = "手機螢幕解析度為: "+dm.widthPixels+" x "+dm.heightPixels;
Builder builder = new Builder(this);
builder.setMessage(optStr);
builder.setIcon(R.drawable.firefox);
builder.setTitle("擷取螢幕像素");
//點擊確定按鈕
builder.setPositiveButton("確定", new DialogInterface.OnClickListener(){
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(GetScreenActivity.this, "擷取到像素", Toast.LENGTH_LONG).show();
}
});
builder.setNegativeButton("返回", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(GetScreenActivity.this, "返回", Toast.LENGTH_LONG).show();
}
});
builder.create().show();
}</SPAN>
