好的，我有一个字符串加密的东西public class MainActivity extends AppCompatActivity {
Button button_clear_canvas;
private PaintView canvas;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
canvas = findViewById(R.id.canvasview);
button_clear_canvas = findViewById(R.id.button_clear_canvas);
button_clear_canvas.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
SaveDialog();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_erase,menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.erase:
CreateDialog();
}
return true;
}
public void SaveDialog(){
AlertDialog.Builder mBuilder = new AlertDialog.Builder(this);
mBuilder.setMessage("Are you sure you want to save?");
mBuilder.setPositiveButton("YES", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
try {
if(canvas.mBitmap != null){
canvas.getEncoded64ImageStringFromBitmap(canvas.mBitmap);
}
} catch (Exception e) {
Log.v("log_tag", e.toString());
}
}
});
mBuilder.setNegativeButton("NO",null);
AlertDialog alertDialog = mBuilder.create();
alertDialog.show();
}
public void CreateDialog(){
AlertDialog.Builder mBuilder = new AlertDialog.Builder(this);
mBuilder.setMessage("Are you sure ?");
mBuilder.setPositiveButton("YES", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
canvas.OnClearCanvas();
}
});
mBuilder.setNegativeButton("NO",null);
AlertDialog alertDialog = mBuilder.create();
alertDialog.show();
}
。
如果不逐一进行，我怎么能把它放在所有字符串上呢？
答案 0 :(得分：2)
您可以使用＆＃34;查找和替换＆＃34;功能还提供对正则表达式的支持。因此，您可以轻松找到所有字符串，捕获它们并使用XorStr()包装。
In＆＃34; Find＆＃34;字段((\".+?\")|('.+?'))将匹配具有双引号或单引号的所有字符串。如果您只想要双引号，请将其缩小为(\".+?\")。
In＆＃34;替换为＆＃34;字段，使用：XorStr($1)。
