本文通過(guò)為大家展示一段示例代碼來(lái)介紹Android開(kāi)發(fā)過(guò)程中如何獲取屏幕像素，相信其在思維上對(duì)大家有一定的幫助。

<span style="font-size:18px;">private void alertScreenDialog() {   
        DisplayMetrics dm = new DisplayMetrics();   
        getWindowManager().getDefaultDisplay().getMetrics(dm);   
        String optStr = "手機(jī)屏幕分辨率為: "+dm.widthPixels+" x "+dm.heightPixels;   
        Builder builder = new Builder(this);   
        builder.setMessage(optStr);   
        builder.setIcon(R.drawable.firefox);   
        builder.setTitle("獲取屏幕像素");   
        //點(diǎn)擊確定按鈕   
        builder.setPositiveButton("確定", new DialogInterface.OnClickListener(){   
            @Override   
            public void onClick(DialogInterface dialog, int which) {   
                Toast.makeText(GetScreenActivity.this, "獲取到像素", 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>
