我想创建一个允许我设置手机墙纸的应用程序,但是getApplicationContext().setWallpaper(bm)
有问题。
它说setWallpaper
已过时,我应该使用另一种方法,但是我不知道该使用哪种方法。
到目前为止,这是我的代码:
package com.example.asus.incercare_proiect;
/**

class bakapp extends Activity implements OnClickListener {
ImageView display;
int tophone;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
// activitatea noastra sa acopere intreg ecranul
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.backapp);
Button but = (Button) findViewById(R.id.setwallpaper);
tophone = R.drawable.image4;
but.setOnClickListener(this);
display = (ImageView) findViewById(R.id.ivdisplay);
ImageView image1 = (ImageView) findViewById(R.id.IVimage1);
ImageView image2 = (ImageView) findViewById(R.id.IVimage2);
ImageView image3 = (ImageView) findViewById(R.id.IVimage3);
ImageView image4 = (ImageView) findViewById(R.id.image4);
ImageView image5 = (ImageView) findViewById(R.id.IVimage5);
image1.setOnClickListener(this);
image2.setOnClickListener(this);
image3.setOnClickListener(this);
image4.setOnClickListener(this);
image5.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast var;
switch (v.getId()) {
case R.id.IVimage1:
display.setImageResource(R.drawable.image4);
var = Toast.makeText(bakapp.this, "image changed",
Toast.LENGTH_SHORT);
var.show();
tophone = R.drawable.image4;
break;
case R.id.IVimage2:
display.setImageResource(R.drawable.image5);
var = Toast.makeText(bakapp.this, "image changed",
Toast.LENGTH_SHORT);
var.show();
tophone = R.drawable.image5;
break;
case R.id.IVimage3:

var.show();
tophone = R.drawable.image6;
break;
case R.id.image4:
display.setImageResource(R.drawable.image7);
var = Toast.makeText(bakapp.this, "image changed",
Toast.LENGTH_SHORT);
var.show();
tophone = R.drawable.image7;
break;
case R.id.IVimage5:
display.setImageResource(R.drawable.image8);
var = Toast.makeText(bakapp.this, "image changed",
Toast.LENGTH_SHORT);
var.show();
tophone = R.drawable.image8;
break;
case R.id.setwallpaper:
// trebuie folosit bitmap
InputStream is = getResources().openRawResource(tophone);
Bitmap bm = BitmapFactory.decodeStream(is);
try {
getApplicationContext().setWallpaper(bm);
// trebuie sa cerem permisiune pentru a seta Wallpaperul
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
var = Toast.makeText(bakapp.this, "Wallpaper image changed",
Toast.LENGTH_SHORT);
var.show();
break;
}
}
}
有人可以帮我吗?
最佳答案
如果查看official docs,您会发现此方法自API 5
起已被弃用,而应该使用WallpaperManager.setBitmap()。
